Between February 1968 and October 1969, three young women — Patricia Docker, Jemima MacDonald, and Helen Puttock — were murdered in Glasgow, Scotland, after each had spent an evening at the Barrowland Ballroom, a popular dance hall. Docker, a 25-year-old auxiliary nurse, was found strangled and beaten in the Battlefield district on 23 February 1968; her handbag and jewellery had been taken from the scene. Eighteen months later, on 17 August 1969, 31-year-old Jemima MacDonald was discovered strangled and beaten in a derelict tenement on MacKeith Street, having last been seen leaving the Barrowland with a well-dressed man. On 31 October 1969, 29-year-old Helen Puttock was found raped and strangled behind a tenement in Scotstoun.

Puttock's sister, Jean Langford, had shared a taxi with Puttock and the suspect after the three left the Barrowland together, providing police with the most detailed account of the man's appearance, speech, and mannerisms, including his repeated Biblical references and condemnation of adultery — the basis for the "Bible John" nickname. This led to Scotland's first Crown Office-authorised publication of a composite drawing of a murder suspect, later supplemented by an artist's portrait and, in 1970, an early use of photofit technology in a Scottish investigation.

The inquiry became one of the largest manhunts in Scottish criminal history, involving over 100 full-time detectives, more than 50,000 witness statements, and over 5,000 suspects questioned in its first year; Langford alone attended more than 300 identity parades without identifying the man she had met. Despite this scale, no perpetrator was ever charged.

Several men have been investigated or named as potential suspects over the decades, including a man referred to by aliases "John Edgar"/"John White," a Netherlands-based man named David Henderson, and John Irvine McInnes, whose body was exhumed in 1996 for DNA testing; McInnes was formally cleared by the Crown in July 1996 and further DNA advances in 2005 disproved any match. Convicted serial killer Peter Tobin was also investigated as a possible suspect following his 2000s murder convictions, under an inquiry known as Operation Anagram, but was eliminated after DNA, timeline, and physical-description discrepancies, according to the senior investigating officer, David Swindle.

A domestic-violence theory has also been raised by a former crime editor, citing detectives who reviewed the case files in the 1980s; both Docker's estranged husband and MacDonald's former husband were questioned by police as possible suspects in their respective cases, though neither was charged. Helen Puttock's husband, George, was excluded via DNA and dental-comparison testing in 1996.

The three murders remain formally unsolved and the case remains open. Jean Langford, the only known witness to have held an extended conversation with the suspect, died in September 2010. No further murders have been conclusively linked to the same perpetrator.
