The Case of the Russian Cross

That happened to be, the last that either of us, actually, saw of Alysia Rimmell, alive.
Ludovic Travers, associate of Scotland Yard, and the director of his own detective agency, is brought into a new case, and finds something very much wrong with an attempt at blackmail, an unsolved theft, and a murder... they all seem to link up. The more he studies them the more he is, convinced that the diamonds, from an elaborate pendant Russian Cross are the root of the whole business, not the pornographic pictures also mixed up in it. By the time the whole, diabolical mystery has unraveled, the reader will agree that the novel, the author's fiftieth Ludovic Travers mystery, is as intriguing and entertaining as ever.
