Dr. Lancelot Priestley is a fictional investigator born in July 1869 in a series of books by

John Rhode Cecil John Charles Street (3 May 1884 – 8 December 1964), who was known to his colleagues, family and friends as John Street, began his military career as an artillery officer in the British Army. During the course of World War I, he became a ...

After 1924, Dr. Priestley took over from Dr. Thorndyke as the leading fictional forensic investigator in Britain, and featured in 72 novels written over 40 years, solving many ingenious and misleading murders. Dr Priestley's involvement is usually at the request of the police but only if the case piques his scientific curiosity; having little, or no, interest in criminal justice. "''Hanslet had brought many problems which confronted him in the course of his duties to Dr. Priestley's notice, usually with results highly satisfactory to himself. But in nearly every case Dr. Priestly's interest in the problem ceased when he had solved it to his own satisfaction. The fate of the criminal was a matter of complete unconcern to him. He treated detection much as he would have treated a game of chess. The pieces in the game had no more than a passing interest to him.

Described in The Ellerby Case, Dr. Priestley's book "Fact and Fallacy" "''..contained in every one of its two hundred odd pages a direct and trenchant attack upon those whom the author was apt to allude to as "The Orthodox Scientific School"'' and "''So the reviews poured in by every post: denunciatory, indignant, sometimes distinctly abusive. And Dr Priestley would sit and gloat over them, as a primitive warrior might gloat over the blood of his adversaries''" In the early books Dr. Priestly provides assistance mainly to his friend Chief Inspector Hanslet. In later books Dr. Priestley becomes an
