The Riddle of the Frozen Flame

Mr. Maverick Narkom, Superintendent of Scotland Yard, sat before the litter of papers upon his desk. His brow was puckered, his fat face red with anxiety, and there was about him the air of one who has reached the end of his tether. He faced the man opposite, and fairly ground his teeth upon his lower lip. "Dash it, Cleek!" he said for the thirty-third time, "I don't know what to make of it, I don't, indeed! The thing's at a deadlock. Hammond reports to me this morning that another bank in Hendon-a little one-horse affair-has been broken into. That makes the third this week, and as usual every piece of gold is gone. Not a bank note touched, not a bond even fingered. And the thief-or thieves-made as clean a get-away as you ever laid your eyes on! I tell you, man, it's enough to send an average person daft! The whole of Scotland Yard's been on the thing, and we haven't traced 'em yet! What do you make of it, old chap?"
