One of Crofts's most highly praised works, which lives up to its reputation with ease. A miser and his servants are burnt to death in Yorkshire; despite the verdict of accident, murder is suggested by the fact that the bank notes, which should have perished in the fire, are still in circulation. French, disguised as an insurance investigator, travels north, and from there to France and Scotland. Despite a great deal of travelling, his plodding detection is genuinely interesting, and, although he only solves the crime a minute before he arrests the murderer, he comes across as more of a thinker than in later tales. The red herrings to which he applies his mind are as fresh as the writing and characterisation; and, although the reader will not be unduly surprised by the final revelation, he will marvel at the intricacy of a highly ingenious plot, with a nice bit of body-snatching for extra merit.
