The Absent Timekeeper

9 min

The Congress's prized chess clock — the brass-cased Vosberg tournament clock donated in 1962, reserved for the top board — vanished from the skittles room between the lunch adjournment and the afternoon session. Without it, board one cannot resume under regulation timing, and four people had reason to be near the felt-lined case where it rested. Trace the clock and the hand that hid it.
