The Two Tickets Puzzle is a 1930 detective novel by the British author Alfred Walter Stewart, published under his pseudonym J.J.

[1] [2] [3] It was the second and last book featuring Superintendent Ross, an attempt to replace the author's better-known series character Sir Clinton Driffield who returned in Connington's next novel The Boathouse Riddle.

With its story of a police detective trying to break down an alibi using railway timetables, it resembled the style of Freeman Wills Crofts' Inspector French series.

A mean-spirited businessman Oswald Preston is discovered shot dead under the seat in an empty compartment of a railway carriage.

Eventually, the work pays off and they are able to unmask the murderer and give chase as he attempts to escape.
