"I had the very devil of a job to get to Stanning. Ever since you've been down here, the Chief has had special men on duty day and night at the police-station there. I didn't dare stop to light the head-lamps and as a result the first thing I did was to charge the front gate and get the back wheel so thoroughly jammed that it took me the best part of twenty minutes to get the blooming car clear. When at last I got to the station, I found that Matthews, the Chief's man, you know, had just arrived by car from London with a lot of plain-clothes men and some military police. He was in the very devil of a stew. He told me that Bellward had escaped, that the Chief was out of town for the night and ungetatable, and that he (Matthews) had come down on his own to prevent the gaff being blown on you and also to recapture Mr. Bellward if he should be mad enough to make for his old quarters.
"I told Matthews of the situation up at the Mill House. Neither of us was able to understand why you had not telephoned for assistance--we only discovered later that the telephone had been disconnected--but I went bail that you were up against a very stiff proposition. I told Matthews that, by surrounding the house, we might capture the whole gang.
"Matthews is a cautious cuss and he wanted a good deal of persuading, so we lost a lot of time. In the end, he wouldn't take my advice to rush every available man to the scene, but only consented to take two plainclothes men and two military police.
He was so precious afraid of upsetting your arrangements. The Chief, it appears, had warned everybody against doing that. So we all piled into the car and I drove them back to the Mill House.
"This time I left the car at the front gate and we went up to the house on foot. We had arranged that Matthews and one of the military police, both armed, should stay and guard the car, while the two plainclothes men and the other military policeman, the corporal here, should accompany me to the house. Matthews believed my yarn that we were only going to 'investigate.' What Iintended to do in reality was to round up the whole blessed lot.
"I put one of the plain-clothes men on the front door and the other round at the back of the house. Their orders were to stop anybody who came out and at the same time to whistle for assistance. The corporal and I went to our old observation post outside the library window.
"The moment I glanced into the room I knew that matters had reached a climax. I saw you--looking pretty blue, old man--facing that woman who seemed to be denouncing you. Max stood beside you with a pistol, and beside him was our friend, Mortimer, with a regular whopper of an automatic. Before I had time to move, the plain-clothes man at the back of the house whistled. He had found the secret door with Bellward and the woman coming out of it.
Then I saw Mortimer fire point-blank at you. I had my gun out in a second, but I was afraid of shooting, for fear of hitting you as you went for the other man.
"But the corporal at my side wasn't worrying much about you. Just as you jumped he put up his gun and let fly at Mortimer with a sense of discrimination which does him infinite credit. He missed Mortimer, but plugged Max plumb through the forehead and my old friend dropped in his tracks right between you and the other fellow. On that we hacked our way through the French window. The corporal found time to have another shot and laid out a tall, odd-looking man...""No. 13," elucidated Desmond.
"... When we got inside we found him dead across the threshold of the door leading into the hall. Behrend we caught hiding in a brush cupboard by the back stairs. As for the others--""Gone?" queried Desmond with a sudden sinking at his heart.
Francis nodded.
"We didn't waste any time getting through that window," he said, "but the catch was stiff and the broken glass was deuced unpleasant. Still, we were too late. You were laid out on the floor; Mortimer, Bellward and the lady had made their lucky escape. And the secret door showed us how they had gone...""But I thought you had a man posted at the back?""Would you believe it? When the shooting began, the infernal idiot must rush round to our assistance, so, of course, Mortimer and Co., nipping out by the secret door, got clear away down the drive. But that is not the worst. Matthews gave them the car!""No!" said Desmond incredulously.
"He did, though," answered Francis. "Mind you, Mortimer had had the presence of mind to throw off his disguise. He presented himself to Matthews as Strangwise. Matthews knows Strangwise quite well: he has often seen him with the Chief.
"'My God, Captain Strangwise,' says Matthews, as the trio appeared, 'What's happened?'
"'You're wanted up at the house immediately, Matthews,' says Strangwise quite excitedly. 'We're to take the car and go for assistance.'
"Matthews had a look at Strangwise's companions, and seeing Bellward, of course, takes him for you. As for the lady, she had a black lace muffler wound about her face.
"'Miss Mackwayte's coming with us, Matthews,' Strangwise says, seeing Matthews look at the lady. That removed the last of any lurking suspicions that old Matthews might have had. He left the military policeman at the gate and tore off like mad up the drive while Strangwise and the others jumped into the car and were away before you could say 'knife.' The military, policeman actually cranked up the car for them!
"When Matthews burst into the library with the story of you and Strangwise and Miss Mackwayte having gone off for help in our only car, I knew we had been sold. You were there, knocked out of time on the floor, in your disguise as Bellward, so I knew that the man with Strangwise was the real Bellward and I consequently deduced that Strangwise was Mortimer and consequently the very man we had to catch.
"We were done brown. If we had had a little more time to think things out, we should have found that motor-bike and I would have gone after the trio myself. But my first idea was to summon aid.
