Shard knew he had found the place.
Outside the broom closet, the chains hung loose, apparently someone had unlocked it before, but the door was tightly shut. Shard tried pulling at it, and the frail wooden door immediately opened a crack.
He instinctively reached for the revolver at his waist, but hesitated for a moment, instead touching the Roder Card in his pocket. After all, this was a school, and Shard did not want to make too much noise by firing a gun. And besides, bullets can't turn corners, but his Roder Card could even trace a pentagram in the air.
Looking around, and taking advantage of the fact that no one was paying attention, Shard quickly slipped into the broom closet. Perhaps because mops were often put away wet, the sizable interior space was damp, about the size of the cloakroom in Shard's house.
To avoid the possibility that the chamber behind the wall was Henry Val's secret chamber, Shard held his breath and took slow, cautious steps.
