Brian Flynn was born in 1885 in Leyton, Essex. He won a scholarship to the City Of London School, and from there went into the civil service. In World War I he served as Special Constable on the Home Front, also teaching “Accountancy, Languages, Maths and Elocution to men, women, boys and girls” in the evenings, and acting in his spare time.

It was a seaside family holiday that inspired Brian Flynn to turn his hand to writing in the mid-twenties. Finding most mystery novels of the time “mediocre in the extreme”, he decided to compose his own. Edith, the author’s wife, encouraged its completion, and after a protracted period finding a publisher, it was eventually released in 1927 by John Hamilton in the UK and Macrae Smith in the U.S. as The Billiard-Room Mystery.

The author died in 1958. In all, he wrote and published 57 mysteries, the vast majority featuring the super-sleuth Anthony Bathurst.
