Talk about weird concepts — E. A. Smithe is a clone of an author from a previous time who lives in a library and can be checked out like a book. Colette Coldbrook’s father died and her brother was murdered. Before being murdered he passed a book (written by Smithe) to Collete that he believed held a secret. So she checked the Smithe clone out of the library to help her discover the secret. Then she disappeared. Smithe sets out to try to find Colette.
It’s a good mystery/SF story. Devious twists and turns and lots of fun along the way.
