“Captain Granet,” he questioner continued, in his calm, emotionless tone, “according to your story you changed your clothes and reached here at the same time as the Zeppelin, after having heard its approach. It is four miles and a half to the Dormy House Club, and that Zeppelin must have been travelling at the rate of at least sixty miles an hour. Is your car capable of miracles?”
“It is capable of sixty miles an hour,” Granet declared.
“Perhaps I may spare you the trouble,” Thomson proceeded drily, “of further explanations, Captain Granet, when I tell you that your car was observed by one of the sentries quite a quarter of an hour before the arrival of the Zeppelins and the lighting of that flare. Your statements, to put it mildly, are irreconcilable with the facts of the case. I must ask you once more if you have any other explanation to give as to your movements last night?”
“What other explanation can I give?” Granet asked, his brain working fiercely. “I have told you the truth. What more can I say?”
“You have told me,” Major Thomson went on, and his voice seemed like the voice of fate, “that you arrived here in hot haste simultaneously with the lighting of that flare and the dropping of the bombs. Not only one of the sentries on guard here, but two other people have given evidence that your car was out there in the lane for at least a quarter of an hour previous to the happenings of which I have just spoken. For the last time, Captain Granet, I must ask you whether you wish to amend your explanation?”
There was a little movement at the further end of the room. A curtain was drawn back and Isabel Worth came slowly towards them. She stood there, the curtains on either side of her, ghastly pale, her hands clasped in front of her, twitching nervously.
“I am very sorry,” she said. “This is all my fault.”
They stared at her in amazement. Only Granet, with an effort, kept his face expressionless. Sir Meyville began to mutter to himself.
“God bless my soul!” he mumbled. “Isabel, what do you want, girl? Can’t you see that we are engaged?”
She took no notice of him. She turned appealingly towards Major Thomson.
