Synopsis by Hal Erickson
Michael Lanyard, the reformed criminal known as the Lone Wolf, is played in this Columbia B picture by the suave Warren William. The script contrives to have Lanyard's faithful butler Jamison (Eric Blore) to be mistaken for his boss by a gang of jewel robbers. They force poor Jamison to participate in the theft of the valuable "Napoleon gems" which Lanyard has been hired to protect. Most of the action takes place during a steamship voyage, allowing Columbia to trot out its standard (but impressive) shipboard sets and to cloud the budget limitations with heavy fog. Secrets of the Lone Wolf was the eighth in Columbia's series based on the mystery stories of Louis Joseph Vance.
