Frenchy Blake

"Frenchy" Blake (first name unrevealed) is a Gotham City criminal, specializing in theft of jewelry.

Jewel Gang
Blake was the leader of his own gang, the membership including Ricky, "Gloves", "Slick" and two other unknown individuals.

Enounter with the Bat-Man and arrest
In May 1939 Blake and his gang pulls of a string of jewel robberies baffling the police, culminating in a fifth robbery stealing jewels worth $100,000. Their sixth robbery was to be at the Vandersmiths' apartment, and Blake sent Ricky and Gloves on that assignment. However, the two were defeated by the Bat-Man, leaving Gloves jailed and Ricky dead.

The newspapers played up the Bat-Man as the leader of the jewel gang, which led Blake to feel secure in further robbery attempts. He sent his remaining gang members to rob the Norton home, but they too were defeated by the Bat-Man and arrested by the police. Blake was thereafter surprised by the Bat-Man at his apartment, who beat him severely and hanged him out of a window, threatening to let him fall to his death lest he wrote a ful confession of his crimes. After a last desperate attempt to overpower the Bat-Man, Blake was bound and delivered to police headquarters, where officer Kelly and his colleague recieved him together with a letter from the Bat-Man to Commissioner Gordon.
