The Gentleman

Commissioner Gordon had just lit the bat signal when Batman arrived.

"Commissioner," Batman said.

"We've got a new criminal on the lose," Gordon said, "He goes by the name The Gentleman."

"What's his M.O?"

"He robbed a jewelry store and everyone inside disappeared. No ransom demands. No bodies."

Batman nodded, "I'll see what I can do."

And with that Batman grapple hooked away. Bruce had heard of The Gentleman, but there was no evidence. All security cameras where he went were erased and every witness disappeared. As Bruce Wayne he could set up a trap by bringing in some expensive jewelry or put some pressure on a few criminals that might know who the Gentleman is.
