Bleeding Hearts (The Gregor Demarkian Holiday Mysteries Book 11)

Demarkian attempts a good deed on Valentine’s Day: saving a neighbor from jail
Psychiatrist Paul Hazzard was renowned for his insights into the human mind, until his wife was savagely murdered. She was stabbed to death with an ornamental dagger, a grisly crime for which Paul was tried but never convicted. Four years later, to escape his greedy family and his former mistress, Paul takes an unlikely lover: the homely, middle-aged Hannah Krekorian. Hannah’s neighbors, including former FBI agent Gregor Demarkian, are charmed by the sudden romance—until they find her holding an antique dagger over Paul’s bloody body. The police are convinced of Hannah’s guilt, but Demarkian knows his neighbor could never stab Paul to death. Hannah’s valentine may be gone, but if Gregor works a miracle, she’ll have something even better come February 14th: her freedom.
