The Book Of Doppelgangers — Wildside Press

The face in the mirror is yours, but ever so slightly different. A shadow haunts your house, but it walks in places you've never gone. You grew up with a boy who had your face and your name, except he always did everything right, while you never could. Evil twins, double images: these are the tales of the Doppelganger: eight outre tales of the doubly weird by J. Sheridan LeFanu, E.T.A. Hoffmann, Algernon Blackwood, Guy de Maupassant, Honore de Balzac, Hans Christian Andersen, Henry James, and Charlotte Perkins Gilman.
