|BW||Iron Ships and Dead Men|
Duke operates Duke's, an eponymously-named wharf bar in San Pedro, Los Angeles, California.
In "Iron Ships and Dead Men", Jaime Sommers investigates the disappearance of Sam Goldman, elder brother of Oscar Goldman, during the Pearl Harbor attack together with the disappearance of a quarter of a million dollars.
It turns out that Duke, a civilian dockworker in 1941, happens to be alone with Sam on the deck when the Japanese attack commences. Sam and Duke must leave the deck, and the closest cover is a hole in the bulkhead. They both jump into the hole.
Sam is killed by a bullet into his back and straight out. Duke discovers cash of thousands, may be half a million, of dollars, in the case brought by Sam. Duke picks it up and runs, but is soon hit on his leg.
Duke must find a way to hide the money for later retrieval. He resorts to throw the case of money into a pump hole. Ship recovery work later seals Sam and the case of money in the bulkhead of the ship. Duke relocates to LA, establishes Duke's, and waits for 36 years until an opportunity arises for him to retrieve the money.
