Batman: Detective Comics #1048

"The Tower" part two unfolds the mysteries of Dr. Wear as a new doctor, Frow, joins Arkham Tower's staff. The Bat-Family is devising a plan to infiltrate the facility, but they may have been outmaneuvered by someone quite familiar with psychiatric facilities—Dr. Harleen Quinzel, also known as Harley Quinn to our readers. In the "House of Gotham" part two, a boy whose parents were murdered by The Joker slips through the system's cracks. Rather than being placed in a care facility for his trauma, he is sent to Arkham Asylum. There, he must navigate a world where villains could either devour him or teach him to survive in a city under Batman's relentless watch.

Key Notes:

First cameo appearance of Dr. Ocean, obscured by shadows.
