The Thirteenth Hour

The seventh 'Whistler' movie and Richard Dix's last screen performance has him as an independent trucker. He's just cleared all debts and is about to start making money and to marry Karen Morley when he gets involved in an accident. It's not his fault, but his witness vanishes. He winds up paying compensation and having his license suspended. He continues taking jobs, but when a driver fails to show up, he drives the truck himself; a mysterious stranger saps him and kills motorcycle cop Regis Toomey. Dix panics and runs, but realizes that he has to prove his innocence, with no clue but a glove.

It's also the last film directed by William Clemens, a decent journeyman, He had entered the movies as an editor, switched to directing in 1936 and made 33 features in a dozen years. He would die in 1980 at the age of 74.

Like the other movies in the series, it's a decent little B feature, taking advantage of Dix's longtime star power. He had been a middling star at Paramount in the silent era, then shifted to RKO with the coming of sound, as one of their major stars. His career began to decline in the middle of the 1930s. When RKO let him go, he switched to Columbia and settled into the comfortable routine of this series. A series of heart attacks caused his retirement, and he would die in 1949 at the age of 56.
