The man lay still unconscious. "Don't raise his head," Hewitt said. "And one of you had best fetch a doctor. He's had a terrible shock." Then turning to Plummer he went on, "As to _how_ they managed the job I'll tell you what I think. First it struck some very clever person that a deal of money might be got by robbing a walk-clerk from a bank. This clever person was one of a clever gang of thieves--perhaps the Hoxton Row gang, as I think I hinted. Now you know quite as well as I do that such a gang will spend any amount of time over a job that promises a big haul, and that for such a job they can always command the necessary capital. There are many most respectable persons living in good style in the suburbs whose chief business lies in financing such ventures, and taking the chief share of the proceeds. Well, this is their plan, carefully and intelligently carried out. They watch Laker, observe the round he takes, and his habits. They find that there is only one of the clerks with whom he does business that he is much acquainted with, and that this clerk is in a bank which is commonly second in Laker's round. The sharpest man among them--and I don't think there's a man in London could do this as well as young Sam Gunter--studies Laker's dress and habits just as an actor studies a character. They take this office and cellar, as we have seen, _because it is next door to a bank whose front entrance is being altered_--a fact which Laker must know from his daily visits. The smart man--Gunter, let us say, and I have other reasons for believing it to be he--makes up precisely like Laker, false moustache, dress, and everything, and waits here with the rest of the gang. One of the gang is dressed in a blue coat with brass buttons, like a hall-porter in Buller's bank. Do you see?" "Yes, I think so. It's pretty clear now."
