Here's a delightful detective spoof in the tradition of "Bugsy Malone."A faltering teenage shamus is handed a package to guard, but he's soon visited by a host of strangers who want it in the worst way. Colin Dale, Susannah York and Dursley McLinden star in this miniature salute to "The Maltese Falcon." AKA: "Just Ask for Diamond." 83 min. Soundtrack: English.
