"But its return?" asked Sir Chichester.
"Simpler still. Your gates were left open last night, and we returned from Harrel at four in the morning. Stella's chauffeur hands in his letter, comes back by the way he went and is home here at Rackham an hour and a half before we thought of saying good-bye to Mrs. Willoughby. That is the way it happened. That is the way it must have happened," Hillyard concluded energetically. "For it's the only way it could have happened."
Luttrell, though he had been a listener and nothing else throughout Martin's statement, had cherished a hope that somehow it might be discovered that Stella had died by an accident. That she should die by her own hand, in this house, under the same roof as Joan, and because of one year which had ended at Stockholm—oh, to him a generation back!—was an idea of irrepressible horror. He could not shake off some sense of guiltiness. He had argued with it all that day, discovering the most excellent contentions, but at the end, not one of them had succeeded in weakening in the least degree his inward conviction that he had his share in Stella's death. Unless her death was an accident, unless, using her drug, she fell asleep and so drifted unintentionally out of life! He still caught at that hope.
"Are you sure that the handwriting was Stella's?" he asked.
"Quite. I saw the letter."
"Did the editor give it to you?"
"No, he had to keep it for his own protection."
"That's a pity," said Harry. A pity—or a relief, since, without that evidence before his eyes, he could still insist upon his pretence.
"Not such a great pity," answered Martin, and taking a letter from his pocket he threw it down upon the table, with the ghost of a smile upon his face. "What do you think I have been doing during the last two years?" he asked drily.
Harry pounced upon the letter and his first glance dispelled his illusion—nay, proved to him that he had never had faith in it. For he saw, without surprise, the broad strokes and the straight up-and-down letters familiar to him of old. Stella had always written rather like a man, a man without character. He had made a joke of it to her in the time before the little jokes aimed by the one at the other had begun to rasp.
