One of the Birds of Prey has gone missing

Tim was sent to meet up with Barbara at her clocktower. Bruce wasn't very trusting of some of the Birds of Prey but he trusted Barbara and that was what mattered. Instead of dealing with this matter personally, he thought it more fitting to have Tim put his detective skills to the test.

"So what's going on Barbara?"

"Tim..." she looked away from her computer briefly.

"It's... not good. One of the Birds of Prey are missing. I have an idea of who took her, but I'll need your help."
