Holiday With Violence — Ellis Peters

English teens on vacation in Italy are caught up in a murderous conspiracy, from the Edgar Award�"winning author of the Chronicles of Brother Cadfael.
 
On a train ride across Northern Italy, a quartet of young English tourists en route to Venice are charmed by a kindly older fellow passenger. Inviting them into his first-class compartment, their new friend, Signore Galassi, beguiles them with stories, anecdotes, and fascinating facts about the lush Italian countryside.
 
But once the train deposits them all in Turin, a dark cloud settles over the Brits' carefree holiday. After discovering that their elderly traveling companion has been brutally attacked and robbed, the distraught students vow to scour this unfamiliar city and find his assailant.
 
Unbeknownst to the young British visitors, they have something in their possession that ties into a greater, even more terrible crime. Their hunt could have unexpected and very deadly consequences, for now their quarry is hunting them.
 
The Edgar, Agatha, and Gold Dagger Award�"winning author of the Brother Cadfael Mysteries is “highly recommended for those who still like a proper five course whodunit with all the trimmings” (The Sunday Times).
