“Humph! That is not the first time that Tomlinson has failed altogether in his duty. However, that does not matter for the moment. What is your own idea, Mr. Thorndyke?” “My idea is that a couple of good men should go down with me to Streatham, and that we should be always on the watch in High Street until we see him ride past. Directly it is dark we will go to his house, fasten the old woman up, and search it thoroughly. If we find stolen property so much the better; but in any case we shall wait inside the house until he returns, and as he comes in throw ourselves upon him before he has time to draw a pistol. I should say it would be as well the men should go down in a trap. There is an empty house next door, and when we go to search the place we can leave the horse and trap inside the gate. Directly we have him secure we can fetch up the trap, put him in, and one of the men and myself can drive him back here, leaving the other in charge of the house, which can then be searched again next day.” “I think that will be a very good plan, and will avoid all unnecessary fuss. I will send Malcolm and Chester down with you tomorrow. Where will you meet them?” “I should say that they had better put up at the Greyhound. I don't suppose he will go out until six or seven o'clock, but they had better be there earlier. One should station himself in the main street, the other concealing himself somewhere beyond the fellow's house, for it is likely enough that sometimes he may take the other way. I will go down to the Greyhound at six, and will wait there until one of them brings me news that he has left.” “I think you had better come in in the morning, and give your instructions to the men; there will be less fear of any mistake being made. I should say you had better put your horse up and come here on foot; one can never be too careful when one is dealing with so crafty a rogue as this; he certainly does not work with an accomplice, but for all that he may have two or three sharp boys in his pay, and they may watch this place by turns and carry him news of any stir about the office.” “I will walk in,” Mark replied. “It is no distance from Stockwell.” Mark slept but little that night. He had believed all along that he should be finally successful, but the discovery had come so suddenly that it had taken him completely by surprise. It might not be the man, and he tried hard to persuade himself that the chances were against his being so, so that he should not feel disappointed should it turn out that it was some other criminal, for that the man was a criminal he had not a shadow of doubt. The next morning he was at the office early. The chief arrived half an hour later, and the two officers were at once called in.
