"We have traced him down to one of his places at last, miss. I said to Andrew, 'We must keep a special sharp look out to-night, for like enough, now that the inquest is over, he will be going to talk over the matter with his pals.' Well, miss, last night, at half-past nine, out he comes. He wasn't in evening dress, for although, as usual, he had a topcoat on, he had light trousers and walking boots. He did not turn the usual way, but went up into Piccadilly. We followed him. I kept close behind him, and Andrew at a distance, so that he should not notice us together. At the Circus he hailed a cab, and as he got in I heard him say to the driver, 'King's Cross Station.' As soon as he had gone off Andrew and I jumped into another cab, and told the man to drive to the same place, and that we would give him a shilling extra if he drove sharp.
"He did drive sharp, and I felt sure that we had got there before our man. I stopped outside the entrance, Andrew went inside. In five minutes he arrived, paid the driver his fare, and went in. I had agreed to wait two or three minutes outside, while Andrew was to be at the ticket office to see where he booked for. I was just going in when, to my surprise, out the man came again and walked briskly away. I ran in and fetched Andrew, and off we went after him. He hadn't more than a minute's start, and we were nearly up to him by the time he had got down to the main road. We kept behind him until we saw him go up Pentonville Hill, then Andrew went on ahead of him and I followed. We agreed that if he looked back, suspicious, I should drop behind. Andrew, when he once got ahead, was to keep about the same distance in front of him, so as to be able to drop behind and take it up instead of me, while I was to cross over the road if I thought that he had discovered I was following him.
"However, it did not seem to strike him that anyone was watching him, and he walked on briskly until he came to a small house standing by itself, and as he turned in we were in time to see that the door was opened to him by a man. Andrew and I consulted. I went in at the gate, took my shoes off, and went round the house. There was only a light in one room, which looked as if there were no servants. The curtains were pulled together inside, and I could see nothing of what was going on. He stopped there for an hour and a half, then came out again, hailed a cab halfway down the hill, and drove off. Andrew and I had compared watches, and he had gone back to Jermyn Street, so that we should be able to know by the time the chap arrived whether he had gone anywhere else on his way back. When I joined him I found that the man must have driven straight to the Circus and then got out, for he walked in just twenty minutes after I had seen him start."
"That is good news indeed, Roberts. We will go and see Mr. Pettigrew directly after breakfast. Please order the carriage to be round at a quarter to ten."
Netta was as pleased as her friend when she heard that a step had been made at last.
"I am sick of this inaction," she said, "and want to be doing something towards getting to the bottom of the affair. I do hope that we shall find some way in which I can be useful."
"I have no doubt at all that you will be very useful when we get fairly on the track. I expect that this will lead to something."
After Tom Roberts had repeated his story to Mr. Pettigrew, Hilda said:
"I brought Roberts with me, Mr. Pettigrew, that he might tell the story in his own way. It seems to me that the best thing now would be to employ a private detective to find out who the man is who lives in Rose Cottage. This would be out of the line of Tom Roberts and Colonel Bulstrode's servant altogether. They would not know how to set about making inquiries, whereas a detective would be at home at such work."
"I quite agree with you," the lawyer said. "To make inquiries without exciting suspicion requires training and practice. An injudicious question might lead to this man being warned that inquiries were being made about him and might ruin the matter altogether. Of course your two men will still keep up their watch. It may be that we shall find it is of more use to follow the track of this man than the other. But you must not be too sanguine; the man at Rose Cottage may be an old acquaintance of Simcoe. Well, my dear," he went on, in answer to a decided shake of the head on Hilda's part, "you must call the man by the only name that he is known by, although it may not belong to him. I grant that the manner in which he drove into King's Cross station and then walked out on foot would seem to show that he was anxious to throw anyone who might be watching him off the scent, and that the visit was, so to speak, a clandestine one. But it may relate to an entirely different matter; for this man may be, for aught we know, an adept in crime, and may be in league with many other doubtful characters."
