"Call Gibbs with an update." Tony told Kate as they moved back to the stairwell to follow the trail up. They had reached the next landing and the blood didn’t go higher, so they went out into the hall. Except there was very little in that hall to see. The blood started at the door to the stairwell and then went down. As Kate dialed Gibbs, Tony started snapping photos, getting the sixth floor stairwell door, down the stairs, and along the fifth floor.
