Here's a very rough and certainly unpolished blurb.
It's 1926. Jack's good at finding places to hide. With the Communists on one side and the Church on the other, a wizard learns to keep his head down. While working the night shift one rainy night, a couple of no-goodnicks walk into Jack's office, turning his life upside down. If he can keep his secret, he should be all right, until a woman walks in. You can't keep a secret from a woman.
