Real talk: we are not big fans of this one. But we *are* big fans of the three dogs discussed herein: 1) fictional dog Bob, our titular “dumb witness” (though whether he ever actually witnessed anything is... questionable); 2) Christie’s real-life faithful companion Peter, to whom this book is dedicated; and 3) actor dog Snubby, for whom David Suchet apparently fell as hard as his version of Hercule Poirot did in the televised adaptation. And it isn’t often we get to celebrate man’s best friend in the course of discussing a murder mystery. We just wish the puzzle mystery could have been more up to Dame Agatha’s habitually high standard.
