Lock Ah Tam and the Chinatown Tragedy

Lock Ah Tam was born in September 1872 in Canton, Southern China. It was the Year of the Monkey, a sign associated with intelligence, confidence and ambition, but also, at times, competitiveness and secrecy. Very few records survive of his early life, and there is nothing in the historical record to tell us what kind of boy he was or what hopes his family may have had for him.

As a young man, he found work as a ship’s steward on a British mail boat, sailing the established trade routes between South China and Britain’s major ports. He learned English fluently and later settled in Cardiff, South Wales, where he ran a boarding house for Chinese sailors near Barry Dock. It was in Cardiff that he met 20-year-old Catherine Morgan, the daughter of local butcher Isaac Morgan and his wife Ellen. The couple married in 1905 and set up home at 218 Bute Road in Tiger Bay, a busy, multicultural dockland district where Greek, Chinese, Irish and French families lived side by side.

 

 

Later that year, in December 1905, their son Lock Ling Ah Tam was born. Their daughter Doris followed in 1906, and two years later came Cecilia. Catherine would give birth to another son, but he died in infancy.

Lock Ah Tam’s Move to Birkenhead

By 1910, the Tams had moved to Birkenhead, across the River Mersey from Liverpool. Birkenhead was a bustling port town, alive with the sounds of the waterfront – men shouting as they hauled cargo, the constant churn of ships, and the cries of gulls overhead. A melange of languages drifted through the dockside streets, carried in with each new arrival. Liverpool was home to one of Europe’s earliest Chinese communities, and many Chinese seamen who had worked for shipping firms like the Blue Funnel Line chose to settle there permanently. Around Pitt Street, Frederick Street and Cleveland Square, boarding houses, cafés and laundries sprang up to serve the growing community, and the district became known as Chinatown. Conditions were often cramped, and some lodging houses held as many as a hundred men, with up to ten sharing a single room. Gambling and opium smoking were common; part of a dockside underworld that thrived in overcrowded back streets.

Tam and Catherine lived in a three-storey house at 122 Price Street in Birkenhead, in a working-class neighbourhood. At this time, Tam was working as an agent for a Hong Kong shipping company, whose office was located above a shop at number 4 Pitt Street in Liverpool. Every morning, he crossed the River Mersey by ferry to reach the office. Alongside this, he was building a reputation as a shrewd and capable businessman. He ran three boarding houses in Pitt Street, earning the nickname, ‘The King of Liverpool’s Chinatown.’ For a short period, Catherine’s married sister, Mary Foo, lived with the family, and they were also joined by a servant, Margaret Sing, known as Maggie.

Lock Ah Tam’s success continued to grow, and he became one of the most prominent figures within the Chinese communities of Liverpool and Birkenhead. He frequently acted as a police interpreter, assisting Chinese sailors who spoke little or no English, and later worked as a supervisor for the Ocean Steamship Company in Birkenhead. On occasion, he helped local police trace Chinese sailors who had deserted their ships. He also founded a social club in Pitt Street, known as the Chinese Republic Social Club, which provided recreation for sailors far from home. Those who knew Tam described him as hardworking, generous, and devoted to his family. However, as his wealth increased, he began keeping guns in the house for protection.

Tam’s daughters, Cecilia and Doris, attended a ladies’ college in Liverpool, and by 1916, Tam had become a naturalised British citizen. He was prosperous enough to send his 11-year-old son, Lock Ling, to school in British-occupied Hong Kong, where he would later qualify as an engineer. It was important to Tam that his son learn Chinese and maintain a connection to his ancestral homeland.

Head Injury, Bankruptcy and Family Tensions

Then, in the summer of 1918, there was an incident that would later take on enormous significance. On 11 August, Tam dropped into his social club for a drink and a game of billiards. At some point during the evening, a group of drunken Russian sailors forced their way inside, and a fight broke out. In the chaos, Tam received a severe blow to the head with a billiard cue, an injury serious enough to confine him to bed for two weeks.

He appeared to recover physically, but those close to him noticed changes in his behaviour. He became increasingly irritable and drank heavily. There were sudden bursts of temper, and on one occasion, he smashed a glass in a pub for no apparent reason. On another, he quarrelled with a taxi driver and had to be restrained, though he apologised afterwards and said he had no memory of the incident. Despite these episodes, he remained outwardly respectable and continued his business activities. At times, he was approached by criminals involved in smuggling opium and cocaine from New York into Liverpool, but he refused to take part.

In 1924, Lock Ah Tam invested £10,000 in a new shipping venture – the equivalent of well over half a million pounds today. The enterprise failed, and he was declared bankrupt. Around the same time, he bought a double-barrelled shotgun and took up game shooting, inviting both Chinese and English friends to shooting parties in the Cheshire countryside.

By now, Doris and Cecilia had both completed their education, and Doris had secured a position as a secretary to a Merseyside businessman. In November 1925, Lock Ling returned home from his studies in Hong Kong. The reunion was not an easy one, as father and son clashed frequently, often over Lock Ling’s late nights and social life. Household tensions began to simmer.

The Murders at Price Street

On Tuesday 1 December 1925, around a dozen guests gathered at the house to celebrate Lock Ling’s return and his 21^st birthday. To the guests, the evening appeared harmonious. At 8:30 p.m., a Cantonese dinner was served, accompanied by champagne and whisky. During the meal, Lock Ah Tam rose to toast his son. Singing and dancing followed, and the guests stayed until just after midnight, in the early hours of Wednesday 2 December.

At 12:50 a.m., Lock Ling had just gone to bed when he heard raised voices from his parents’ room. Alarmed, he and his sisters went downstairs, finding their father in a state of agitation, shouting and gesturing wildly. An argument erupted. Lock Ling accused him of striking their mother, which Tam furiously denied. When Lock Ling threatened to take his mother away from the house to safety, Tam ordered everyone out of the room. Catherine and her daughters withdrew to the first floor sitting room, while Lock Ling ran out of the house to fetch a neighbour.

At that point, the servant, Maggie Sing, was woken by Tam calling, ‘Maggie, come downstairs and get my boots from the parlour’. But as she passed Tam’s bedroom, she caught sight of his reflection in the mirror. He was holding a revolver. Instead of continuing to the parlour, she ran to the sitting room, where she found Catherine in tears, being comforted by her daughters. Breathlessly, Maggie told them what she had seen, and together, the four women pushed furniture against the door, barricading themselves inside. Moments later, Tam pounded on the door, demanding to be let in. They sat in terrified silence until the pounding stopped and his footsteps retreated. Everything fell quiet. Believing the danger had passed, the women removed the barricade and went into the kitchen.

Lock Ling had just returned from next door, bringing their neighbour, Mrs Louisa Chiu. He ushered her, Maggie, and his sister Doris into the back scullery, leaving Cecilia and their mother in the kitchen. He then ran off again to fetch a policeman. Then, everything seemed to happen at once. A gunshot rang out from just outside the room, and Cecilia saw her mother collapse to the floor. A second shot struck Cecilia in the neck. Lock Ling heard the shot and turned back towards the house, catching a glimpse of his father in the kitchen window, wielding a shotgun and revolver. Lock Ling grabbed an old brass kettle lying in the yard and flung it through the window, hoping to distract his father, then continued as fast as he could to the police station.

Doris and Maggie clung to each other in the scullery and Doris screamed, ‘Oh daddy, what have you done?’ Tam made no reply. He opened the scullery door and fired twice with the revolver at his daughter’s head. Leaving Maggie and Mrs Chiu sobbing but alive, Tam returned to his room, put the weapons away, then came downstairs calmly. He then went out into the street and used the telephone box to call the police. By now, it was 1:45 a.m.

Tam Calls the Police

‘I have shot my wife and children,’ he announced. The startled operator immediately connected him to Birkenhead police station. Tam told the officer on duty, ‘Send your folks please. I have killed my wife and daughters. My house is 122 Price Street.’ The police would later find bloodstains in the phone box.

An eerie silence settled over the house while Tam waited for the police. When he opened the door, he said simply, ‘Come in officers, I have done my wife in.’ Catherine, aged 40, and Cecilia, aged 17, were pronounced dead at the scene, while 19-year-old Doris would later die of her injuries at Birkenhead Hospital on 21 January 1926.

Tam offered little explanation to the officers, though he remarked, ‘The trouble was through my son. My wife has not a kind word for me, and my son is the cause of it.’ His state of mind that night became a central focus of the investigation and the trial that followed. He was charged with three counts of murder, and the trial opened at Chester Assizes on Friday 5 February 1926.

The Trial of Lock Ah Tam

Sir Ellis Griffith led for the crown. A police sergeant recalled that Tam had appeared calm when he was arrested at his home, but a senior police officer told the court that when he was brought into the police station, Tam’s hands were trembling and his eyes bulging. Lock Ling gave evidence that his father had been drunk on the night of the murders, though he added that he was a good husband and father when sober. The attending sergeant maintained that Tam had not been intoxicated at the time of his arrest, though party guests confirmed he had been drinking champagne and whisky. One, a Belgian toymaker named Frank Denye agreed with the sergeant, saying he did not believe Tam had been under the influence.

Tam’s friends, family, and the wider Chinese community raised funds to secure the renowned defence barrister Sir Edward Marshall Hall, hiring him with the largest legal fee paid in a murder case at that time. Marshall Hall entered a plea of not guilty on the grounds of insanity, arguing that the 1918 head injury from the billiard cue had affected Tam’s brain and left him susceptible to seizures. He added that the stress of losing a substantial sum in a failed business venture had further strained the defendant’s mind. The barrister urged the court to consider that no sane man would commit murder without motive and then phone the police calmly afterwards. Dr Ernest Reeve, from a psychiatric hospital in Lancashire, testified that Tam had experienced a state of ‘unconscious automatism’ due to epilepsy, aggravated by alcohol. In his passionate closing speech, Marshall Hall told the courtroom, ‘It turned a man – a mild, lovable and peaceable man – into a raving mad man….absolutely and entirely motiveless, he killed those whom he loved best. Yes, there is no doubt he did it, but at the time he did it, he was insane.’

Two prison medical officers challenged the defence’s medical evidence, arguing that the crime was committed under the influence of alcohol rather than insanity. They suggested Tam had been motivated by jealousy over his son’s position and influence in the household.

Jury’s Verdict and Appeal

The jury deliberated for just 15 minutes before returning a guilty verdict. Tam showed no emotion as Mr Justice McKinnon pronounced the death sentence, though some newspapers reported that tears were seen running down the judge’s face as he delivered the sentence.

The subsequent appeal failed. Although 100,000 people signed a petition for reprieve, the Home Secretary refused. 53-year-old Lock Ah Tam was scheduled to be hanged on Tuesday 23 March 1926, 10 days after the Chinese New Year – the year of the Tiger. A friend who visited him in prison later reported that the condemned man had begged, ‘If I am hanged, get my body out and bury me with my wife and daughters.’

Lock Ling visited his father the night before the execution. Tam’s final words to his solicitor were, ‘I know now that I have done wrong, although I did not know at the time and I have no recollection of doing anything. If I have done wrong, however, they must do with me what the law orders them to do.’

Execution

The execution went ahead on 23 March 1926 at Walton Jail, Liverpool, carried out by executioner William Willis. Tam’s last request was denied, and he was buried not with his family, but within the prison walls. Afterwards, one of Catherine Tam’s sisters delivered flowers to the prison gates, requesting they be placed on Lock Ah Tam’s grave; a small act of compassion which reflected the depth of feeling the family still held for him despite his actions.

Burial and Legacy

In Flaybrick Hill Cemetery in Birkenhead, a tall granite headstone marks the grave of Catherine and her daughters. Tam had chosen the monument in 1910, when his one-month-old son had died in infancy and was buried there.

Today, the area of Liverpool’s Chinatown around Pitt Street, where Lock Ah Tam once had his office, was heavily damaged during the Blitz. Redevelopment and wartime destruction forced the Chinese community to relocate slightly further south, around Nelson Street, where Liverpool’s modern Chinatown now stands. Walton Jail was also damaged by bombs, and the murder house at 122 Price Street no longer exists.

A waxwork of Lock Ah Tam was displayed at the Victoria Hotel in Pontypridd, South Wales, standing alongside notorious murderers such as ‘Brides in the Bath’ killer George Smith, and Frederick Deeming, who some suspected of being Jack the Ripper.

Lock Ling Ah Tam, the sole surviving member of the family, is difficult to trace in historical records. He likely married a woman of mixed Chinese and Welsh ancestry named Annie Helena Lowfat, and eventually left Britain to settle in China.

The case remains full of questions, and some journalists speculated about a Chinese curse surrounding the events. Two unsettling coincidences were reported in the press: a clock at the Chinese club in Pitt Street, a gift from Tam, reportedly stopped at exactly 12:50 a.m. on the night of the murders. On the day of Tam’s sentencing at Chester Assizes, the family’s 22-year-old cockatoo collapsed and died in its cage. The strange occurrences continued. Within a year of the execution, crown prosecutor Sir Ellis Griffith died of apoplexy in a hotel room, and defender Sir Edward Marshall Hall died of heart failure.

Whatever the cause of these coincidences, the case itself remains a tragic instance of three deaths. Catherine, Doris, and Cecilia Tam were murdered by the person they trusted most. Lock Ah Tam, husband and father, had been successful and respected in his community and had worked hard to provide his children with a good education. Whether his violent outburst stemmed from his earlier head injury, the humiliation of the failed investment and the money he lost, or the tensions created by his son’s return from Hong Kong and the shifting roles within the household, we cannot say for certain. He may have felt he was losing control, something that, for a man of his generation, could have struck at the heart of his identity. In the end, it may have been a combination of factors. Either way, the result was a profoundly disturbing tragedy.
