The Two Tickets Puzzle (Murder Room)

'Mr J. J. Connington is a name revered by all specialists on detective fiction' Spectator When Oswald F. Preston is shot dead on the 10.35 local train from Horston, two obvious suspects are immediately in the frame: his wife's lover and an employer with a grudge. With red herrings a-plenty, and a number of other contenders for murderer, including a young heiress, Superintendant Ross has his work cut out for him.
