It took more than half an hour, but by the time Vince left for lunch we had learned that there was nothing to learn from Kyle's finger. The cut was extremely clean and professional, done with a very sharp instrument that left no trace behind in the wound. There was nothing under the fingernail except a little dirt that could have come from anywhere. I removed the ring, but we found no threads or hairs or telltale fabric swatches, and Kyle had somehow failed to etch an address or phone number onto the inside of the ring. Kyle's blood type was AB positive.
