This was the letter that Vernon read standing in the shadow of the arch by the concierge's window. The concierge had hailed him as he hurried through to climb the wide shallow stairs and to keep his appointment with Betty when she should leave the atelier.

"But yes, Mademoiselle had departed this morning at nine o'clock. To which station? To the Gare St. Lazare. Yes—Mademoiselle had charged her to remit the billet to Monsieur. No, Mademoiselle had not left any address. But perhaps chez Madame Bianchi?"

But chez Madame Bianchi there was no further news. The so amiable Mademoiselle Desmond had paid her account, had embraced Madame, and—Voila! she was gone. One divined that she had been called suddenly to return to the family roof. A sudden illness of Monsieur her father without doubt.

Could some faint jasmine memory have lingered on the staircase? Or was it some subtler echo of Lady St. Craye's personality that clung there? Abruptly, as he passed Betty's door, the suspicion stung him. Had the Jasmine lady had any hand in this sudden departure?

"Pooh—nonsense!" he said. But all the same he paused at the concierge's window.

"I am desolated to have deranged Madame,"—gold coin changed hands.—"A lady came to see Mademoiselle this morning, is it not?"

"No, no lady had visited Mademoiselle to-day: no one at all in effect."

"Nor last night—very late?"

"No, monsieur," the woman answered meaningly; "no visitor came in last night except Monsieur himself and he came, not to see Mademoiselle, that understands itself, but to see Monsieur Beauchèsne an troisième. No—I am quite sure—I never deceive myself. And Mademoiselle has had no letters since three days. Thanks a thousand times, Monsieur. Good morning."

She locked up the gold piece in the little drawer where already lay the hundred franc note that Lady St. Craye had given her at six o'clock that morning.
