I glanced at the surroundings. About the oblong excavation was a tangled mass of herbage, peas and beans with fading leaves, for it was in the corner of a kitchen-garden, which in the fall of the previous year had been allowed to run wild. And in such a position had the grave been dug that it was entirely concealed.
That it had been purposely prepared for Lola was apparent. She had been invited there to her death!
Had it not been for my fortunate presence, combined with the fact that Stevens had called just at the opportune moment, then the dainty little girl who, against her will, was the cat's paw of the most daring and dangerous gang of criminals in Europe, would be lying there concealed beneath that long tangle of vegetables and weeds.
"The house has been to let for nearly three years," the sergeant informed me. "But this hole has only been recently dug, a little over a week, we think. It was probably on the evening previous to your adventure, sir."
"Probably," I said, for the earth looked still fresh, though the rain had caked it somewhat. Two spades were lying near, therefore, I conjectured, the work had been accomplished by two men. The two I had seen with Gregory, I presumed.
"We're making inquiries regarding the intruders," the sergeant went on. "I only wish Mr. Warton were here, but he had to go up to the Yard this morning. Can't you give any description of the people you saw here?"
"I thought you had described them, Stevens," I said, addressing the taxi-driver.
"So I have, sir. But in the dark I wasn't able to see very much."
"Well," I exclaimed, in reply to the sergeant, "I, too, did not have much opportunity of seeing them. The electric light was switched off the moment I entered and I was shot by the aid of an electric torch. I had no means of defending myself. I fired at the light at the time, it's true, but the scoundrel evidently held it away from him, knowing that I might shoot."
I did not intend to assist the police. The Criminal Investigation Department never showed very great eagerness to assist me in any of my investigations.
