Ray used a pair of needle-nose pliers to lift a tiny black toggle switch out of an evidence baggie.

“That was mounted inside the drywall cavity,” Ray said.

“Four inches under the faceplate.”

Daniel leaned in over the bench.

“A manual kill switch.”

“Flip that toggle,” Ray said, “and every jack on the second floor loses its dial tone in an instant.”

“And where did the line go once the toggle was flipped?” Daniel asked.

Ray set the meter down on the wooden workbench.
