The Two Tickets Puzzle

A man is found murdered on a train and Superintendent Ross is on the case. This is a classic fair play mystery that will be enjoyed by every reader who wants to pit their wits against the detective. About this story the London Daily Mail wrote: For those who ask first of all in a detective story for exact and mathematical accuracy in the construction of the plot there is no author to equal the distinguished scientist who writes under the name of J. J. Connington. His latest story is the most complex and ingenious he has yet written. The Two Tickets Puzzle was published in 1930. The Coachwhip edition includes an introduction by Curtis Evans.
