A.A. Milne 
The Red Door Mystery 

The Red House, stately mansion home of Mark Ablett, is filled with very proper guests when Mark’s most improper brother returns from Australia. When the maid hears an argument in the study it isn’t long before the brother dies… of a bullet between the eyes! Strangely, the study has been locked from the inside, and Mark Ablett is missing. Only an investigator with remarkable powers of observation could hope to resolve this mystery, and Antony Gillingham (with cheerful Bill Beverly at his side) is just the man.
