The Poisson Case. By Freeman Wills Crofts. (Collins. 7s. 6d.

net.)—A most admirable detective story in which the mystery of the first chapter is cleverly elucidated. The convolu- tions of the plot carry the reader with breathless interest through nearly three hundred pages, and not the least of the excellences of the book is that the investigations are carried out by a real Scotland Yard inspector, and no " gifted amateur " gets any chance to meddle with the problem. It is obvious that in a book of this kind all attempts at describing the plot are most unfair, a we can only refer any reader who wishes for nearly three hours of entertaining reading to the volume itself.
