Benny Breakiron: Madame Adolphine (Benny Breakiron #2)

Madame Adolphine is a kind, gentle old lady, and a good friend of the super-strong Benny Breakiron. So why is she robbing a bank, banging a man on the head with a mallet, and being thrown in the trunk of a car, with no memory of what happened? It's up to Benny to get to the bottom of it... and stop it if he can.
