Batman: Death and the Maidens

It's been twenty-five years since Bruce Wayne's parents were gunned down in Crime Alley and he's worried that he doesn't remember his mother anymore. This more than anthing else, is why the potion given to him by Ra's al Ghul tempts him.

Nyssa, a woman with a connection to the Demon's Head going back centuries has come to warn him not to trust Ra's gifts. Alfred has tried to warn him off of his temptation, but Bruce has ever been his own man. Drinking the potion, he finds himself once more in Crime Alley... with Martha Wayne.

But Nyssa is at work with her own plans. After surreptitiously befriending Talia, and gaining her trust, she and her servant Misha have abducted Ra's daughter.
