"I told you the name of the party I am after, Mr. Telfer," Plummer said, "and I went straight to Mr. Martin Hewitt, as being most likely to have information of him. Mr. Hewitt, whose name you know already, of course, is kind enough, seeing we're in a bad pinch, and pushed for time, to come in and give us all the help he can. Both he and his friend, Mr. Brett, know a good deal of the doings of the person we're after, and their assistance is likely to be of the very greatest value. Do you mind giving Mr. Hewitt any information he may ask? I must rush over to the Yard to put some other inquiries on foot, and to set an observation or two, but I'll be back presently." "Certainly," Mr. Telfer answered, "I'm only too anxious to give any information whatever--so long as it is nothing departmentally forbidden--which will help to put this horrible matter right. Please ask me anything, and be patient if my answers are not very clear. I have been much overworked lately, as you may imagine, and have had very little sleep; and now this terrible misfortune has upset me completely; for, of course, I am held responsible for that copy of the code, and if it isn't recovered, and quickly, I am ruined--to say nothing, of course, of the far more serious consequences in other directions." "That is the safe in which it was kept, I presume?" Hewitt said, indicating a small one let into the wall. "May I examine it?" "Certainly." Mr. Telfer turned and produced the keys from his pocket. "The code was here, lying on this shelf when I needed it this morning at ten. I took it out, used it, returned it to the same place exactly, and locked the safe door. Then I took the draft of the telegram, together with the copy in cypher, into the Controller's room, gave it into safe hands, and returned here." Hewitt narrowly examined the lock of the safe with his pocket lens. "There are no signs of the lock having been picked," he said, "even if that were possible. As a matter of fact, this is a lock that would take half a day to pick, even with a heavy bag of tools. No, I don't think that was the way of it. You have no doubt about locking the safe door at 10.20, I suppose, before you went to the Controller's room?" "No possible doubt whatever. You see, I left the whole bunch of keys hanging in the lock while I coded the telegram. It was a short one, and was soon done. Then I returned the code to its place, locked the safe, and then used another key on the bunch to lock a drawer in this desk. I had no occasion to go to the safe again till about 12.20, when the Controller's secretary came here with a telegram to be de-coded. The safe was still locked then, but when it was opened the code was gone." "You had had no occasion to go to the safe in the meantime?" "None at all. I locked it at 10.20, and I unlocked it two hours later, and that was all." "You were not in the room the whole of the time, of course?"
