Quantum Marlowe

"I'm just that kinda guy..."
Pete Marlowe, a tiny but tough private detective, has had a bad day. Two mad scientists, Montez and Muck, abducted him, lopped off his pinky finger, and installed a red button that enables him to walk through walls. Targeting Pete because his con-artist Uncle Flynn secretly unloaded the Blarney Stone on the Pope, they send Pete in with his detachable finger to get it back, snaring him in a secret plot that involves the Vatican, church bells, a Mexican drug cartel, and a World War II Nazi project called Die Glocke. Can Pinky survive M&M's quantum mechanics? Or is he destined to be marooned in another dimension?
"When Pinky gives them the finger, they stay fingered."
