Dating from 1916, and apparently written with the help of a retired Scotland Yard detective, this tale of the murder of a judge with an unedifying "secret life" is both fascinating and frustrating.
It is frustrating due to the writing style, expansive, repetitive and prolix even for its time, which mires the plot in unnecessary descriptive matter and stifles appreciation of its ingenuity and, I think, originality. Frustrating, too, is the depiction of obstinate and wrongheaded professional detectives, mulishly sticking to preconceived notions of guilt.
The fascination is in the presentation of multiple solutions, and in the depiction of a subtle and clever private detective who also often gets it wrong.
In the hands of more stylish writers and with an axe-wielding editor, this would have been a gem of a mystery. As it is, it can only be appreciated with ruthless skipping and speed reading through the more turgid passages.
It is recommendable and worthwhile and I shall certainly attempt another.
