"On his way to Dover!" repeated the émigré. "But, Mr. Elphinstone, René did not go to Dover! He crossed from Harwich to Germany, of course."
"I think you must be mistaken, sir," replied the old gentleman mildly. "His letter came from Canterbury, at all events. It bears the postmark. But what is wrong then?"
For La Vireville was on his feet, looking very grave. "Have you the letter here?"
Considerably astonished, Mr. Elphinstone took it out of his pocket. "This is what he says: 'I have just met, by chance, two very old friends of my family, who have been living here, it appears, for a couple of years or so—Mme. and Mlle. de Chaulnes. They are very anxious to make Anne's acquaintance, and I have promised them that they should do so as soon as possible. If, therefore, you would send him to Canterbury with Elspeth for a few days on receipt of this, I should be greatly obliged. He would be well looked after.' And enclosed was an invitation from the French lady herself."
La Vireville gave a cry. "It wanted only this! Good God, sir, what have you done? Mme. de Chaulnes—the poor child!" He almost snatched the letter from the old man's astonished hand and took it to the window. "Yes, a very good imitation, though—pardon me—you ought to know your son-in-law's handwriting better . . . Mon Dieu, what a disaster! When did the boy go?"
"Last Wednesday," answered Mr. Elphinstone, looking dazed. "But what in God's name do you mean, M. de la Vireville? He got there safely. I have even had a letter from him to-day in which he speaks of the two kind ladies—see, 'The two old ladies who are very gentle to me'—he means kind, gentil; he often uses that expression—'and their grey cat.' So it is all true, and he is there. . . . I do not understand you."
"Of course he got there safely—would to God he had not!" exclaimed La Vireville in a sort of desperation. "But, all the same, those two kind old ladies are spies in the pay of the Convention. We have only recently discovered it, to our cost. And clever! . . . How did they get their information—know that René was leaving England just at this time, even know the name of Anne's nurse?"
"It must be all right," reiterated Mr. Elphinstone piteously. "No one could have told them but René himself."
"Mr. Elphinstone, I repeat, René never went to Canterbury! I myself set him a mile or two on his way to Harwich. That is the one mistake these women have made, or, it may be, a risk that they deliberately ran, trusting that you would not know the route your son-in-law took—as you did not. As for the rest, there has been treachery somewhere—in the house, almost certainly. . . . I warned René. . . . However, time is too valuable to spend in finding out who sold them information. The more pressing matter is to get the child back before it is too late."
Mr. Elphinstone put his hand to his head. "Too late! . . . I still do not understand. What could they do to him?"
