"There were giants—everybody knows it," growled Max Fortin.

"And you a chemist!" I observed scornfully.

"Listen, Monsieur Darrel," squeaked Le Bihan; "you know yourself that the Purple Emperor was a scientific man. Now suppose I should tell you that he always refused to include in his collection a Death's Messenger?"

"A what?" I exclaimed.

"You know what I mean—that moth that flies by night; some call it the Death's Head, but in St. Gildas we call it 'Death's Messenger.'"

"Oh!" said I, "you mean that big sphinx moth that is commonly known as the 'death's-head moth.' Why the mischief should the people here call it death's messenger?"

"For hundreds of years it has been known as death's messenger in St. Gildas," said Max Fortin. "Even Froissart speaks of it in his commentaries on Jacques Sorgue's Chronicles. The book is in your library."

"Sorgue? And who was Jacques Sorgue? I never read his book."

"Jacques Sorgue was the son of some unfrocked priest—I forget. It was during the crusades."

"Good Heavens!" I burst out, "I've been hearing of nothing but crusades and priests and death and sorcery ever since I kicked that skull into the gravel pit, and I am tired of it, I tell you frankly. One would think we lived in the dark ages. Do you know what year of our Lord it is, Le Bihan?"
