Everything seems to be going right for Julian Spencer. The brilliance of the young composer's work is beginning to be recognized, and he is engaged to marry a beautiful woman. There's just one thing that stands in the way of his happiness. In the attic, behind a locked door, lives Julian's monstrous half-brother, the deformed result of a mad scientist's botched experiment, a creature with a ravenous, insatiable appetite for raw, bloody meat . . . G. S. Marlowe's bizarre horror novel I Am Your Brother (1935) was published to positive reviews from bemused critics, who admitted they had no idea what the book was actually about, and became a cult favorite in the 1930s. This edition reproduces the original jacket art by Rex Whistler and includes a new introduction by Phil Baker, who casts a new light on the book's obscure author.
