Okay, it’s possible: now punch holes in it. That’s easy. Why risk the hard option at all? Blake knew I was coming back to the safe house to resume my duties in less than twenty-two hours. Why not wait for me to jander into the safe house, straight into a crossfire or into the sights of a single sniper? Why load for bear and come visiting? (Unless he also had reason to suspect I had no intention of ever coming back and was actually heading for the hills. But set that one aside for later: one riddle at a time here.)
