Once again the retired jewel thief uses his skills to help out those in need.
Joan (Jean Muir) is an honest working girl who is due to marry into a wealthy family. She is entrusted with some valuable jewels but soon finds herself accused of murder when someone tries to steal her jewels, but the thief is himself killed by someone else! Jean enlists the help of The Lone Wolf Michael Lanyard (Warren William) and his trusty butler Jamison (Eric Blore).
The Lone Wolf discovers that the location of the jewels was only known to a small number of people, one of those must be the murderer/thief but whom. As usual Inspector Crane (Thurston Hall) is only interested in arresting the Lone Wolf!
This is an excellent entry in the Lone Wolf series with plenty of sleuthing and red herrings. It also has the usual humour, fast moving action and interplay between the Lone Wolf and Jamison which makes this series so enjoyable.
