In an uncharacteristically strategic move, I decided to read The ABC Murders for the Serial/Spree Killer square instead of 13, handily netting me two more bingos in the fifth column and corresponding diagonal. They'll probably be my last, unless I can slip in one more sneaky bingo before the end.
Hercule Porgot sends his regards and would like to inquire the reason I've shoved a detestable bubble pipe in his mouth. (Because I could. Obviously.)
