Trying to prank his secretary when he phones in, Sam hints at the clue that his latest case revolves around. Arriving in the office, Effie shares a little confusing family history with her hardboiled boss. In flashback Sam recounts his meeting with a client who needs him to protect a valuable and artistically made cup. On the train, Sam fends off would be robbers, but he’s only successful until he gets a thump on the head.
Waking up to a body, Sam finds the cup missing, his client dead, and a slap in the face from a woman claiming to be the wife of the clients partner. Twists in the story intrigue Sam, especially when things are nothing as they appear in the relationship between client, wife, lover, and cup.
Which cup is the valuable one, the real one, or the fake one? The guns come out as Sam works with the cops to lay a trap designed to catch a killer. That doesn’t mean the danger is over for our hero, fist fights, and even an encounter with chloroform awaits him. To get to the hard evidence he needs, Sam even finds him out at sea.
Sam explains it all as he wraps up his report in real time with Effie Perine.
