These are my favourites from last year:
The Case for Easter, Lee Strobel
Short and snappy, a good quick evangelistic read. Could be read comfortably in a couple of hours.
Sleeping Murder, Agatha Christie
A spooky murder mystery that has been lying dormant. Obviously waiting for Miss Marple to come along and solve it.
They do it with Mirrors, Agatha Christie
Miss Marple appears again to solve a murder that is rather theatrically carried out.
