"But look at it, sir," insisted Rampole, and bent over the paper suddenly. "Old Anthony didn't know he was doing a cross-word puzzle; but, in effect, that's what it is. You said it was, a form of the rebus―"

"Come to think of it," rumbled Dr. Fell, clearing his throat, "the process was not unknown―"

"Well, work it!" said Sir Benjamin. "Try it that way. `What called the dwellers of Lyn-dun?' I supposed that means, `What were the dwellers of Lyn-dun called?' Does anybody know?"

Dr. Fell, who had been puffing out his moustache and acting like a sulky child, took up the pencil again. He answered, shortly:

" `Fenmen,' of course. Very well, we'll try it. As Miss Starberth has suggested, our next two words are `Iliad' and `Norway.' `What doth all men destroy?' I can't think of anything except Death. So there we are — FENMEN ILIAD NORWAY DEATH."

Then a broad grin creased up the folds of his many chins. He twisted his 'moustache like a pirate.
