subtlety that he does not appreciate. He has learned his law in the orderly-room, where the qualifications to practise are an irritable temper and a loud voice. However, the practical point is, inspector, that the warrant is irregular. You can't arrest people for hypothetical crimes."
The officer drew a deep breath of relief. He knew all about the irregularity, and now joyfully took refuge behind Thorndyke's great reputation.
When he had departed—with a brief note from my colleague to the General—Thorndyke slipped his arm through mine, and we strolled towards the house.
"This is a grim business, Jervis," said he. "That boy has got to be found for everybody's sake. Can you come with me when you have had some food?"
"Of course I can. I have been saving myself all the afternoon with a view to continuing the search."
"Good," said Thorndyke. "Then come in and feed."
A nondescript meal, half tea and half dinner, was already prepared, and Mrs. Hanshaw, grave but self-possessed, presided at the table.
"Mabel is still out with Giles, searching for the boy," she said. "You have heard what she has done!"
I nodded.
"It was dreadful of her," continued Mrs. Hanshaw, "but she is half mad, poor thing. You might run up and say a few kind words to poor Lucy while I make the tea."
I went up at once and knocked at Miss Haldean's door, and, being bidden to enter, found her lying on the sofa, red-eyed and pale, the very ghost of the merry, laughing girl who had gone out with me in the morning. I drew up a chair, and sat down by her side, and as I took the hand she held out to me, she said:
"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
