The Night of the Monkeys
Lorenzo Beccati

Ventimiglia, 1936. In the castle of Serge Voronoff, eighty monkeys are locked in a case and used by scientists for organ transplant procedures between animals and humans. One night, the quiet of the castle is shattered by an unusual murder. Called to investigate is Martin Giles, a sharp but conventional private detective.
Despite his presence, the killings don’t stop, sparking suspicion and hatred among the castle’s inhabitants. Is the killer hiding among them? In a series of twists and turns, the inevitable conclusion will shock everyone—but no one more than the detective himself, Martin Giles.
