This was pretty bad.
OMG. William Gargan in this installment is Ellery. I already am blanking on the plot. A person of interest dies at the same time a mummy case is stolen from a museum.
For some reason, Ellery thinks the body is in the cemetery. He and Margaret Lindsay go to a cemetery - don't ask me how they know which one - not only that, but they go directly to a mausoleum where they find the body.
This is a wartime film, so it turns out there's a group of Nazi spies running a health club, and they're after gold which is supposed to help the Dutch Resistance. Gilbert Roland has a miniscule part. I think he's the one who is killed.
Odd. I call it odd.
