This book was passed on to me by Tigus, along with a Frederic Brown mystery called Madball, which I read for Halloween Bingo.
This was a delightfully funny and convoluted mystery. The MC, Leonidas Witherall, runs a boys school, writes mysteries in secret, and looks so much like Shakespeare that his nickname is Bill. When a package wrapped in brown paper goes missing from his office while he is in the home, hijinks ensue as he attempts to recover it.
There is mayhem. There are shenanigans. There is a dead body and a kidnapped secretary and a random meeting with a long-forgotten friend.
Lots and lots of fun. Thanks for sending it to me, Tigus!
