This book was bor-ring. It is supposed to be about some evil secret society, but after about fifty pages I gave up, as almost nothing had happened. This book was especially disappointing because I had just read his The Corpse in the Waxworks, written some thirty years before this one, and it was a brisk and inventive detective novel of the locked-room category for which Carr is justifiably famous.
