Barbara has gone quiet. Nightwing should investigate.

Nightwing was dropped off a few blocks away from Barbara’s clock tower. Batman sped off to go deal with a shooting in progress leaving Dick to investigate alone. He found nothing odd about the tower from the outside. There were no signs of a break-in so he proceeded to enter the usual way. Through a hidden door in the roofing. He dropped in and saw that there had definitely been a struggle. Her desk had been knocked over, scattering papers and other objects all over the floor.
