A Peculiar Combination by Ashley Weaver

Crime didn’t disappear from London during World War II; it actually became easier for opportunists during the blackouts.

The orphaned girl was schooled by her affable uncle to be an ace safecracker and lock picker, and she’s become a deft accomplice.

We’re not meant to think of them as bad people; though they move in shady circles, they rob from the rich without getting violent—not the worst strategy during hard times.
