Heather Graham - Cafferty & Quinn (#1-2)

Let the Dead Sleep (Cafferty and Quinn #1)
It was stolen from a New Orleans grave—the centuries-old bust of an evil man, a demonic man. It's an object desired by collectors and by those with wickedness in their hearts.

One day, its current owner shows up at Danni Cafferty's antiques shop on Royal Street, the shop she inherited from her father. But before Danni can buy the statue, it disappears and the owner is found dead….

Michael Quinn, former cop and now private investigator, is determined to find and destroy this object with its long history of evil and even longer trail of death. He and Danni are drawn together in their search for the missing statue, following it through sultry New Orleans nights to hidden places in the French Quarter and secret ceremonies on abandoned plantations.

But Cafferty and Quinn know that their story won't end when this case is closed and the dead rest in peace once again.

Waking the Dead (Cafferty and Quinn #2)
In the case of Ghosts in the Mind painted by Henry Sebastian Hubert, that's more than just an expression. The characters are reputed to come to life—and to kill. The artist was a friend of Lord Byron and Mary Shelley, joining them in Switzerland in 1816, and now, almost two hundred years later, the painting appears in New Orleans. Wherever it goes, death seems to follow.

Danielle Cafferty and Michael Quinn, occasional partners in solving crime, are drawn into the case. They begin to make connections between that summer in Switzerland and this spring in Louisiana. Danni, the owner of an eccentric antique shop, and Quinn, a private detective, have discovered that they have separate but complementary talents when it comes to investigating unusual situations.

Blending their personal relationship with the professional lives they've stumbled into, they confront this work of art…and evil. They have to discover what brings it to life. And they have to destroy it—before it destroys them.
