The Lone Wolf Keeps a Date 1940

Retired jewel thief and unofficial private detective Michael Lanyard Warren William, known to fans as the Lone Wolf, has just added a rare Cuban stamp to his coveted collection and chides his loyal butler, Jamison Eric Blore, for winning money in a rigged Havana dice game. His path crosses with the glamorous and wary Patricia Lawrence Frances Robinson as they share their horse-drawn carriage to the airport and board a flying boat bound for Miami.

At the bustling Miami airport, the pair are ambushed by the criminal duo Chimp Edward Gargan and Mr. Lee Lester Matthews, two members of the scheme fronted by the ruthless Big Joe Brady Don Beddoe. The Lone Wolf dashes through the chaos with Patricia, slipping away from the ambushers and keeping their secret safe while she clings to hope and danger at once.

Patricia confides a chilling detail: one of her boyfriend Scotty Bruce Bennett’s clients was killed after hiring Scotty to forward a package stuffed with $100,000 in banknotes. The case widens its grip as Inspector Crane Thurston Hall and his buffoonish associate Dickens Fred Kelsey, along with Miami police captain Moon Jed Prouty, close in on Lanyard’s movements. The detective remains one step ahead, sensing that someone has looted his prized stamp collection while the hunter becomes the hunted.

With that realization, Lanyard races to prove his innocence and unravel the tangled web surrounding Brady and his accomplices. The chase is a dance of wits—dodges, decoys, and near-misses—through crowded streets, shadowy docks, and glamorous rooms, as the Lone Wolf works to expose the triad of villains and recover the missing stamps. He won’t surrender Patricia to fear, nor will he reveal Scotty’s name to those who mean him harm.

In a flurry of double-crosses and clever switches, the Lone Wolf threads the needle: he brings Brady’s operation into the light, unmasking the conspiracy that tied the stolen stamp, the tremulous romance between Lanyard and Patricia, and the fate of Scotty’s client. By the end, Michael Lanyard clears his own name and proves Scotty’s innocence, restoring peace to Patricia’s heart and reaffirming the Lone Wolf’s reputation as a clever, fearless finder of truth in a world full of shadow.
