The Excursion to Tindari
(book #5 of the Inspector Montalbano series)
by Andrea Camilleri. Another good read, in fact, this one is so far the best of the 5 I
have read. The story mostly is how Inspector Montalbano puts the clues together
for a murder of a young man and the disappearance of an elderly couple which at
first seem unrelated, but turn into a pretty sordid scheme.
