“I saw mention of it. Dr. Savaronoff, the Russian champion, was one of the players, and the other, who succumbed to heart failure, was the brilliant young American, Gilmour Wilson.”

“Quite right. Savaronoff beat Rubinstein and became Russian champion some years ago. Wilson was said to be a second Capablanca.”

“A very curious occurrence,” mused Poirot. “If I mistake not, you have a particular interest in the matter?”

Japp gave a rather embarrassed laugh.

“You’ve hit it, Moosior Poirot. I’m puzzled. Wilson was sound as a bell⁠—no trace of heart trouble. His death is quite inexplicable.”

“You suspect Dr. Savaronoff of putting him out of the way?” I cried.
