laughed as he shook the hand of his quondam pupil. "Come, come, Batson, "said he," don't make me out such a bird of ill-omen."
"I was afraid something awkward might have occurred, police job or inquest or something of that sort."
"You weren't so very far wrong," said Thorndyke. "When you are at liberty I'll tell you about it."
"I'm at liberty now," said Batson, dropping into a chair and glaring at Thorndyke through his spectacles. "No scandal, I hope."
Thorndyke reassured him on this point and gave him a brief account of my adventure and our proposed visit to the works; to which he listened with occasional ejaculations of astonishment and relief. "By Gum!" he exclaimed, "what a mercy you got there in time. If you hadn't there'd have been an inquest and a devil of a fuss. I should never have heard the last of it. Ruined the practice and worried me into a lunatic asylum. Oh, and about those works. I wouldn't go there if I were you."
"Why not?" Thorndyke asked.
"Well, you may have to answer some awkward questions, and we don't want this affair to get about, you know. No use raising a dust. Rumpus of any kind plays the deuce with a medical practice."
Thorndyke smiled at my principal's frank egoism. "Jervis and I went over last night," said he, "and had a hasty look round and we found the place quite deserted. Probably it is so still."
"Then you won't be able to get in. How jer get in last night?"
"I happened to have a piece of stiff wire in my pocket," Thorndyke replied impassively.
"Ha!" said Batson. "Wire, eh? Picklock in fact. I wouldn't, if I were you. Devil of a bobbery if anyone sees you. Hallo! There goes the bell. Patient. Let him wait. 'Tisn't six yet, is it?"
"Two minutes past," replied Thorndyke, rising and looking at his watch. "Perhaps we had better be starting as it's now dark, and the business at the works, if there is any, is probably over for the day."
"Hang the works!" exclaimed Batson. "I wouldn't go nosing about there. What's the good? Jardine's alright and the chappie isn't likely to be on view. You'll only raise a stink for nothing and bring in a crowd of beastly reports humming about the place. There's that damn bell again. Well, if you won't stay, perhaps you'll look me up some other time. Always d'lighted to see you. Jervis too. You're not going, Jardine. I've got to settle up with you and bear your report."
"I'll look in later," said I; "when you've finished the evening's work."
"Right you are," said Batson, opening the door and adroitly edging us out. "Sorry you can't stay. Good-night! Good-night!"
He shepherded us persuasively and compellingly down the hall, with a skill born of long practice with garrulous patients, and, having exchanged us on the doorstep for a stout woman with two children, returned into the house with his prey and was lost to sight.
VII. An Unseen Enemy
From my late principal's house we walked away quickly down the lamplit street, all, I think, dimly amused at the circumstances of our departure. "Is Batson always like that?" Thorndyke asked.
"Always," I replied. "Hurry and bustle are his normal states."
"Dear, dear," commented Thorndyke, "what a terrible amount of time he must waste. Of course, one can understand now how that cremation muddle came about. Your incurable hustler is always thinking of the things he has got to do next instead of the thing that he is doing at the moment. By the way, Jardine, I am taking it for granted that you would like to inspect these premises. It is not essential. Jervis and I had a preliminary look round last night, and I daresay we picked up most of the facts that are likely to be of importance if we should be going farther into the matter."
"I think it would be as well for me to take a look at the place and show you exactly where and how the affair happened."
"I think so too," said Thorndyke. "It was all pretty evident, but you might be able to show us something that we had overlooked. Here we are. I wonder if Mr. Gill is on the premises—supposing him still to frequent them."
He looked up and down the street, and, taking a key from his pocket, inserted it into the lock. "Why, how on earth did you get the key?" I asked.
Thorndyke looked at me slyly. "We keep a tame mechanic," said he, as he turned the key and opened the wicket.
"Yes, but how did he get the pattern of the lock?" I asked.
Thorndyke laughed softly. "It is only a simple trade lock. The fact is, Jardine, that in our branch of practice we have occasionally to take some rather irregular proceedings. For instance, I usually carry a small set of picklocks—fortunately for you. That is how I got in last night. Then I never go abroad without a little box of moulding wax; a most invaluable material, Jardine, for collecting certain kinds of evidence. Well, with a slip of wood and a bit of wax I was able to furnish my man with the necessary data for filing up a blank key. One doesn't want to be seen using a picklock. Now, can you show us the way?"
He flashed a pocket electric lamp on the ground, and we advanced over the rough cobbles until we reached a door at the side. "This is where I went in," said I. "It opens into a sort of corridor, and at the end is a door opening on some steps that lead down to the passage below."
Thorndyke tried the handle of the door and pushed, but it was evidently locked or bolted. "I left this door unlocked last night," said he; "so it is clear that someone has been here since. I hardly expected that. I thought our friend would have cleared off for good. But it is possible that Gill had nothing to do with the attempt. The premises may have been used by someone who happened to know that they were unoccupied. It would have been quite easy for such a person to gain admittance; as you see."
While speaking, he had produced from his pocket a little bunch of skeleton keys, with one of which he now quietly unlocked the door. "These builders' locks," said he, "are merely symbolic of security. You are not expected to unfasten them without authority, but you can if you like and happen to have a bit of stiff wire."
We entered the corridor, and, as we proceeded, looked into the rooms that opened out of it. One of them was meagrely furnished as an office, but the thick layer of dust on the desk and stools showed clearly that it had been long disused; the other rooms were empty and desolate, and showed no trace of use or occupation. "The worthy Gill," said Jervis, "seems to have been able, like Diogenes, to get on with a very modest outfit."
"Yes," agreed Thorndyke, "it is a little difficult to guess what his occupation is. The place looks as if it had never been used at all. Shall I go first?"
He halted for a moment, passing the light of his lamp over the massive door at the head of the steps, and then began to descend. It was certainly a horrible and repulsive place, especially to my eyes, with the recollection of my late experience fresh in my mind. The rough brick walls, covered with the crumbling remains of old white-wash, the black masses of cobwebs that drooped like funereal stalactites from the ceiling, the fungi that sprouted in corners, and the snail-tracks that glistened in the lamplight on the stone floor, all contributed to a vault-like sepulchral effect that was most unpleasantly suggestive of what might have been and very nearly had been.
My late prison was easily distinguished by the two holes in the door. We looked in; but that
