Thorne Smith 
Stray Lamb [PDF ebook] 

In The Stray Lamb, author Thorne Smith draws inspiration from his most famous works, the beloved Topper series. In this novel, yet another unhappy banker, T. Lawrence Lamb, experiences a reawakening as the result of a mystical experience — in this case, the sudden ability to take on different animal forms. Lamb uses his newfound powers to fuel a series of madcap misadventures — and even finds love along the way.
