The problem here may have been that I recently read, and much enjoyed, Rhode's Peril at Cranbury Hall. Certainly this outing for Dr Priestley paled in comparison.
After an interesting start in which the body of a dead man is found in the back of the car of a drunk driver stopped by the police, this slips into a rather unwieldy and routine procedural, albeit that the police are heavily guided by the amateur detective.
The American writer and detective novel reviewer Todd Downing wrote:-
"The murder of old Mr Coningsworth is an ingenious one, but the author has not shown equal ingenuity in concealing the identity of the murderer. If the reader cannot identify him before he has read half the book he had better quit reading detective stories."
The full solution, however, requires a huge amount of back story and a late dumping of information which I found dull and trying. The whole was rather reminiscent of some Sherlock Holmes stories, but Conan Doyle does it so much better and more succinctly.
Dr Priestley himself says:-
"But I, in my turn, must make a confession that I would not utter if Harold were present. My deductions were based very largely on conjecture, unsupported by proof."
This is not John Rhode at his ingenious best and one which would be off-putting for new readers.
The edition has a general Introduction by Curtis Evans and a number of typos which are irritating.
