Carr, John Dickson — The Case of the Constant Suicides.

Penguin, 1955. Mass Market Paperback, Second reprint of the first edition. 192pp, the paper tanning a little with age. Green and white softback covers, a little worn to the ends of the spine. A previous owner has written a couple of sentences on one page, objecting to the solution of the crime, otherwise internally clean and tight. Crime - Dr Fell and the mysterious deaths in a castle in Scotland... Very Good.
