Tracking the Beast (A Steve Martinez Mystery)

When the skeleton of a little girl tumbles
out of a hopper car in Omaha, Porcupine
County Sheriff Steve Martinez has a
troublesome case on his hands. The case
gets even more vexing when three more
bodies turn up in hopper cars at the same
remote siding. Two are young girls, but
one is a grown man shot in the back of
the head.
After Steve and his comrades sweat
the initial spadework, the heavy-footed
FBI moves in, as it always does in cases
of child abduction and murder. The Feds
focus on a single Unsub, but when more
adult corpses turn up in hopper cars elsewhere,
Steve suspects that the killer—or
killers—hired someone else to dispose of
them.
With the help of state troopers, deputies,
tribal police, game wardens, the
Ontario Provincial Police and even a
couple of Detroit mobsters, Steve doggedly
goes on the track of what the cops
come to call “the Beast.”
