''The Corpse in the Green Pyjamas'' is a classic 1935 mystery novel by R.A.J. Walling, featuring his recurring detective  Philip Tolefree, about a baffling case where a corpse appears and disappears, challenging Tolefree to unravel hidden truths and impossible logistics, noted for its intriguing plot and vintage charm.  Three completely unrelated events, occurring on the same day, but in different places, create the puzzle for Tolefree’s new adventure: A. Lord and Lady Meriden decide to sell their famous Murillo triptych; B. Sir Isaac Stratton cashes a check for three thousand pounds; C. A tabby cat finds a dark corner for the business on which she is bent. Now the Meridens knew nothing of Sir Isaac’s check; Sir Isaac was unaware of the cat's existence; and the cat was indifferent to everyone and everything. Because of these three events, Tolefree found himself, one night, peering down at a corpse in green pyjamas. How the corpse had got there was one problem; how and whereto it vanished forty minutes after he found it was another. “Hallucinations!” sneered the Honorable John Meriden, but Tolefree thought not, and set out to prove that he was right. ''The Corpse In The Green Pyjamas'' is one of Mr. Walling’s best.
