Our first step was to engage the services of an artist in “makeup.” He was a little man, with a quaint birdlike turn of the head, not unlike Poirot’s own. He considered me some time in silence, and then fell to work. When I looked at myself in the glass half an hour afterwards, I was amazed. Special shoes caused me to stand at least two inches taller, and the coat I wore was arranged so as to give me a long, lank, weedy look. My eyebrows had been cunningly altered, giving a totally different expression to my face, I wore pads in my cheeks, and the deep tan of my face was a thing of the past. My moustache had gone, and a gold tooth was prominent on one side of my mouth.

“Your name,” said Poirot, “is Arthur Neville. God guard you, my friend⁠—for I fear that you go into perilous places.”

It was with a beating heart that I presented myself at the Savoy, at an hour named by Mr. Ryland, and asked to see the great man.
