In this Philo Vance film from Warner Brothers and director Bruce H. Humberstone, Warren William stars as the famous detective.
A group of wealthy people are partying at the Stamm household, and apparently several people are upset that Bernice Stamm (Margaret Lindsay) is planning to marry Monty Montague for reasons that seem to have nothing to do with love, but that she will not reveal. She's actually in love with Dale Leland (Lyle Talbot), who confronts her about it, and her brother is so upset he is drinking himself into a stupor. The guests assemble at the Dragon Pool - a kind of dammed stream - for some late night swimming. But when Monty dives in he never comes out. The police are called by Leland, who suspects foul play. The next day Monty's body is found a good distance from the pool with claw marks on his throat. There is a myth surrounding the pool about a flying dragon, a prehistoric creature, who still lives in the area. Is Philo Vance about to go X-Files in this installment? Watch and find out.
Warren William is very smooth and debonair in the role of Vance, but he spends lots of time picking on and insulting Sgt. Heath (Eugene Pallette) where in previous film installments, Vance and Heath were allied and treated each other as peers. Of course, William Powell was playing the famous detective in those previous films, and Warren William always played even his roles as a protagonist as a bit caddish.
Although Vance systematically interviews witnesses and investigates clues, the final deductions that he makes seem to come out of nowhere. And the actual killer makes a complete confession when he really hasn't been found out at that point at all. Released right after the production code began to be enforced, it seems robbed of the hard bitten situations and dialogue you would expect from a similar film just the year before. It does have its charms though. Warren William is always fun to watch, though Robert Warwick steals the show as a coroner who gets cranky if he is called to a crime scene and there is no corpse.
