From the back cover:
The roadster screeched to a halt.
A Cadillac was blocking the road. Suddenly a masked figure leaped from the big car, a gun in its hand.
Patience Thumm screamed, then struggled to open her car door. But the gun came down sharply on her knuckles.
“Give me the letter,” the masked figure commanded.
When Inspector Thumm was given a thousand dollars to guard a letter, he thought that someone was playing a practical joke. But when a masked stranger threatened his daughter, the inspector knew he had been handed a case loaded with intrigue and death.
