In keeping with an accidental theme—my first case involved a full stop, my second a comma—this may well be the first mystery ever solved by Comic Sans.

Some detectives, perhaps, solve crimes like fireworks: one lit fuse exploding everything at once. I solve crimes like a ten-car rear-ender on a bumper-to-bumper freeway: one car slams into another, and another and another, all the way up the line.
