Mr. Wood has already completed many details that most people would leave until later. In the ”kitchen” (a dusty landing littered with tools), a piece of PVC pipe is built into the only wall. Peering through it, one’s eye is guided to another pipe in an exterior wall 20 feet away. Through these pipes the viewer can read the clock on the Williamsburg Bank more than a mile away. My kitchen clock said Mr. Wood.
