The author of the Jimmie Dale adventures is Frank L. Packard. It began
as an intriguing tale of a young man who would break into safes at night
to retaliate against the owner and give stolen money to the victims of
his crimes. He was discovered by a woman, who then sent him letters with
instructions on where to do it. After some time, the same situation
started to repeat itself. And when he eventually discovered who she was
and fell in love, it seemed like the conclusion was overly sentimental.
The main character of the book, Jimmie Dale, also known as the Gray
Seal, is an expert safe-cracking vigilante. He patrols the streets
preventing criminal acts by thugs, returning stolen property, and
defending the underprivileged. The cops and all the thieves he's stopped
are after him since he always ends up looking like a criminal, which
occurs in New York City. Awesome scenes at Chang Foo's opium den in
Chinatown, colorful terminology, and a little amount of repetition.
