Who Killed Charmian Karslake‪?‬

"Owing to the sudden death of Miss Charmian Karslake this theatre is closed until further notice. Money for tickets already booked will be refunded."
Who killed Charmian Karslake, the famous American actress, on the night of the ball at Hepton Abbey? Who was the mysterious Peter Hailsham who had been present at the ball and had since vanished into thin air? What was his connection, if any, with the respectable County family of Penn-Moreton at whose house the murder had taken place?
How Inspector Stoddart and his assistant Harbord solve these questions, and the surprising discoveries they make in the course of their investigations, form the basis for one of their most devilish mysteries.
Who Killed Charmian Karslake? is the third of Annie Haynes' Inspector Stoddart Mysteries. First published in 1929, it was out of print for over 80 years until this new edition, which also features an introduction by crime fiction historian Curtis Evans.
"A model detective story…a good mental exercise for the distracted reader who has just received his Super-Tax Demand. (The publishers) have again produced a good book." London Mercury
