and the thin white lips move silently and rapidly, from seven to nine, and back again to seven.
"There is something on the cards that puzzles you," says Raymond, breaking the deathly silence. "What is it?"
"A death!" answers the passionless voice of Monsieur Blurosset. "A violent death, which bears no outward sign of violence. I said, did I not, that the king of spades was in danger?"
"You did."
From three to five, from five to nine, from nine to seven, from seven to nine: the groups of cards form a circle: three times round the circle, as the sun goes; back again, and three times round the circle in a contrary direction: across the circle from three to seven, from seven to five, from five to nine, and the blue spectacles come to a dead stop at nine.

But for all that, Heaven save the man who has injured her from the light of such a smile as hers of to-night.
"You want my assistance in some matters of chemistry?" asks Blurosset.
"Yes! I forgot to tell you, madame, that my friend Laurent Blurosset—though he chooses to hide himself in one of the most obscure streets of Paris—is perhaps one of the greatest men in this mighty city. He is a chemist who will one day work a revolution in the chemical science; but he is a fanatic, madame, or, let me rather say, he is a lover, and his crucible is his mistress. This blind devotion to a science is surely only another form of the world's great madness—love! Who knows what bright eyes a problem in Euclid may have replaced? Who can
