Blackie shops for jewelry, but it’s all way too expensive. The clerk has a special deal. A necklace worth $10000 that he’ll let go for just 10 cents. Hey, it’s not hot or anything is it?

The clerk backs down after he realizes the wrong person gave the password. Being Boston Blacki makes it all the worse. When the clerk is killed, Blackie shares what he knows with Inspector Farraday. Before the clerk died, he left a letter that tells all. Now it’s a matter of who finds it first.

As it turns out, the letter has been destroyed, but Blackie has a plan to lure the bad guys out of hiding.

For people not familiar with Blackie’s background, he’s a reformed jewel theif and safe cracker. Which is the reason Farraday is so gruff with him, and often blames him for crimes. Sometimes it takes a thief to catch a theif, and Blackie is about to take a few of them down.
