The next morning Charles had the notebook open before I had even peeled the lid off my container.

The left-hand column held times.

7:12, 11:40, 3:05, 4:50, in that small, square handwriting.

I had spent the morning sorting through the folder Derek had left behind.

One of those receipts had been stamped 3:05 in the afternoon.

“What are those times for?” I asked.
