"It is good of you to come and see a miserable wretch like me. And Jane has been so sweet to me, Dr. Jervis; but Aunt Mabel thinks I have killed Freddy—you know she does—and it was really my fault that he was lost. I shall never forgive myself!"
She burst into a passion of sobbing, and I proceeded to chide her gently.
"You are a silly little woman," I said, "to take this nonsense to heart as you are doing. Your aunt is not responsible just now, as you must know; but when we bring the boy home she shall make you a handsome apology. I will see to that."
She pressed my hand gratefully, and as the bell now rang for tea, I bade her have courage and went downstairs.
"You need not trouble about the practice," said Mrs. Hanshaw, as I concluded my lightning repast, and Thorndyke went off to get our bicycles. "Dr. Symons has heard of our trouble, and has called to say that he will take anything that turns up; so we shall expect you when we see you."
"How do you like Thorndyke?" I asked.
"He is quite charming," she replied enthusiastically; "so tactful and kind, and so handsome, too. You didn't tell us that. But here he is. Good-bye, and good luck."
She pressed my hand, and I went out into the drive, where Thorndyke and the coachman were standing with three bicycles.
"I see you have brought your outfit," I said as we turned into the road; for Thorndyke's machine bore a large canvas-covered case strapped on to a strong bracket.
"Yes; there are many things that we may want on a quest of this kind. How did you find Miss Haldean?"
"Very miserable, poor girl. By the way, have you heard anything about her pecuniary interest in the child's death?"
"Yes," said Thorndyke. "It appears that the late Mr. Haldean used up all his brains on his business, and had none left for the making of his will—as often happens. He left almost the whole of his property—about eighty thousand pounds—to his son, the widow to have a life-interest in it. He also left to his late brother's daughter, Lucy, fifty pounds a year, and to his surviving brother Percy, who seems to have been a good-for-nothing, a hundred a year for life. But—and here is the utter folly of the thing—if the son should die, the property was to be equally divided between the brother and the niece, with the exception of five hundred a year for life to the widow. It was an insane arrangement."
"Quite," I agreed, "and a very dangerous one for Lucy Haldean, as things are at present."
"Very; especially if anything should have happened to the child."
"What are you going to do now?" I inquired, seeing that Thorndyke rode on as if with a definite purpose.
"There is a footpath through the wood," he replied. "I want to examine that. And there is a house behind the wood which I should like to see."
"The house of the mysterious stranger," I suggested.
"Precisely. Mysterious and solitary strangers invite inquiry."
We drew up at the entrance to the footpath, leaving Willett the coachman in charge of the three machines, and proceeded up the narrow track. As we went, Thorndyke looked back at the prints of our feet, and nodded approvingly.
"This soft loam," he remarked, "yields beautifully clear impressions, and yesterday's rain has made it perfect."
We had not gone far when we perceived a set of footprints which I recognized, as did Thorndyke also, for he remarked: "Miss Haldean—running, and alone." Presently we met them again, crossing in the opposite direction, together with the prints of small shoes with very high heels. "Mrs. Haldean on the track of her niece," was Thorndyke's comment; and a minute later we encountered them both again, accompanied by my own footprints.
"The boy does not seem to have crossed the path at all," I remarked as we walked on, keeping off the track itself to avoid confusing the footprints.
"We shall know when we have examined the whole length," replied Thorndyke, plodding on with his eyes on the ground. "Ha! here is something new," he added, stopping short and stooping down eagerly—"a man with a thick stick—a smallish man, rather lame. Notice the difference between the two feet, and the peculiar way in which he uses his stick. Yes, Jervis, there is a great deal to interest us in these footprints. Do you notice anything very suggestive about them?"
"Nothing but what you have mentioned," I replied. "What do you mean?"
"Well, first there is the very singular character of the prints themselves, which we will consider presently. You observe that this man came down the path, and at this point turned off into the wood; then he returned from the wood and went up the path again. The imposition of the prints makes that clear. But now look at the two sets of prints, and compare them. Do you notice any difference?"
"The returning footprints seem more distinct—better impressions."
"Yes; they are noticeably deeper. But there is something else." He produced a spring tape from his pocket, and took half a dozen measurements. "You see," he said, "the first set of footprints have a stride of twenty-one inches from heel to heel—a short stride; but he is a smallish man, and lame; the returning ones have a stride of only nineteen and a half inches; hence the returning footprints are deeper than the others, and the steps are shorter. What do you make of that?"
"It would suggest that he was carrying a burden when he returned," I replied.
"Yes; and a heavy one, to make that difference in the depth. I think I will get you to go and fetch Willett and the bicycles."
I strode off down the path to the entrance, and, taking possession of Thorndyke's machine, with its precious case of instruments, bade Willett follow with the other two.
When I returned, my colleague was standing with his hands behind him, gazing with intense preoccupation at the footprints. He looked up sharply as we approached, and called out to us to keep off the path if possible.
"Stay here with the machines, Willett," said he. "You and I, Jervis, must go and see where our friend went to when he left the path, and what was the burden that he picked up."
We struck off into the wood, where last year's dead leaves made the footprints almost indistinguishable, and followed the faint double track for a long distance between the dense clumps of bushes. Suddenly my eye caught, beside the double trail, a third row of tracks, smaller in size and closer together. Thorndyke had seen them, too, and already his measuring-tape was in his hand.
"Eleven and a half inches to the stride," said he. "That will be the boy, Jervis. But the light is getting weak. We must press on quickly, or we shall lose it."
Some fifty yards farther on, the man's tracks ceased abruptly, but the small ones continued alone; and we followed them as rapidly as we could in the fading light.
"There can be no reasonable doubt that these are the child's tracks," said Thorndyke; "but I should like to find a definite footprint to make the identification absolutely certain."
A few seconds later he halted with an exclamation, and stooped on one knee. A little heap of fresh earth from the surface-burrow of a mole had been thrown up over the dead leaves; and fairly planted on it was the clean and sharp impression of a diminutive foot, with a rubber heel showing a central star. Thorndyke drew from his pocket a tiny shoe, and pressed it on the soft earth beside the footprint; and when he raised it the second impression was identical with the first.
"The boy had two pairs of shoes exactly alike," he said, "so I borrowed one of the duplicate pair."
He turned, and began to retrace his steps rapidly, following our own fresh tracks, and stopping only once to point out the place where the unknown man had picked the child up. When we regained the path we proceeded without delay until we emerged from the wood within a hundred yards of the cottage.
"I see Mrs. Haldean has been here with Giles," remarked Thorndyke, as he pushed open the garden-gate. "I wonder if they
