"Enderby had to live with his conscience, for there were no witnesses of his crime—but who was the man who sat beside him in the taxicab?"
- Since he was born in Montréal, the Canadian Encyclopedia would naturally have an article about prolific pulpster Leslie Gordon Barnard (HERE).
- Barnard generated dozens of pulp stories in the Western, detective, and romance genres over a span of forty-four years, but "The Man in the Taxi" seems to be his sole contribution
to Weird Tales; FictionMags has a list of the 17 stories featuring his only series character,
Mr. Philibus, in Detective Fiction Weekly and Detective Story Magazine (1928-1935). One of his other stories saw republication in EQMM, "Shooting a Line," 1963 (from 1946); while two original ones appeared in AHMM, "The Last Voyage" and "The Talkative Stranger," both 1957.
