When I locked the front door from the outside, I took one of the heavy manila envelopes, pulled out a strip of wide packing tape, and plastered it right across the center of the dark wood paneling at eye level. Above it, I had written five words in black permanent marker so nobody could possibly miss it before they tried the handle. Then I walked down the concrete steps, got into the passenger seat of Martha’s car, and didn’t even look back as we backed out of the driveway and headed north toward the lake.
