"Two months in bed, Major; will that suit you?"

"Too long. A fortnight."

"Done."

The two adversaries took up their positions. At the second encounter, the editor of the Echo de France fell, wounded in the chest.

"Oh, that's too bad of you, Perenna!" growled the Comte d'Astrignac. "You promised me—"

"And I've kept my promise, Major."

The doctors were examining the injured man. Presently one of them rose and said:

"It's nothing. Three weeks' rest, at most. Only a third of an inch more, and he would have been done for."

"Yes, but that third of an inch isn't there," murmured Perenna.

Still followed by the detectives' motor cab, Don Luis returned to the Faubourg Saint-Germain; and it was then that an incident occurred which was to puzzle him greatly and throw a most extraordinary light on the article in the Echo de France.
