"It is just as well not to run any risks in these days when the country is so unsettled," said the detective dryly.
"Especially where a lady is concerned!" remarked Graham significantly.
"I suppose I should have taken Miss Hollister with me and left her in the cab while I transacted my business at the War Department!" said Barnard with self-reproach in his tones.
"They would have only done the same thing in front of the War Department," said the detective convincingly. "They had it all planned to get those notes somehow. You only made it a trifle easier for them by letting the lady go alone. If they hadn't succeeded here, they would have followed you to your home and got into your office or your safe. They are determined, desperate men. We've been watching them for some time, letting them work till we could find out who was behind them. To-night we caught the whole bunch red-handed, thanks to the lady's cleverness. But you had better not risk her alone again when there's anything like this on hand. She might not come out so easy next time!"
Graham muttered a fervent applause in a low tone to this advice, tucking the lap robes closer about the girl. Barnard gave little shudders of apology as he humbly shouldered the blame:
"Oh, no, of course not! I certainly am so sorry!" But Shirley suddenly roused herself to explain:
"Indeed, you mustn't any of you blame Mr. Barnard. He did the perfectly right and natural thing. He always trusts me to look after my notes, even in the most important cases; and I heard the warning as much as he did. It was my business to be on the lookout! I'm old enough and have read enough in the papers about spies and ruffians. I ought to have known there was something wrong when that boy ordered me back and said Mr. Barnard had sent me word. I ought to have known Mr. Barnard would never do that. I did know just as soon as I stopped to think. The trouble was I was giving half my attention to looking at the strange sights out of the window and thinking what I would tell the folks at home about Washington, or I would not have got into such a position. I insist that you shall not blame yourself, Mr. Barnard. It is a secretary's business to be on her job and not be out having a good time when she is on a business trip. I hadn't got beyond the city limits before I knew exactly what I ought to have done. I should have asked that boy more questions, and I should have got right out of that car and told him to tell you I would wait in the station till you came for me. It troubled me from the start that you had sent for me that way. It wasn't like you."
Then they turned their questions upon her, and she had to tell the whole story of her capture, Graham and Barnard exclaiming indignantly as she went on, the detective sitting grim and serious, nodding his approval now and then. Graham's attitude toward her grew more tender and protective. Once or twice as she told of her situation in the old house, or spoke of how the man dragged her along in the dark, he set his teeth and drew his breath hard, saying in an undertone: "The villain!" And there was that in the way that he looked at her that made Shirley hasten through the story, because of the wild, joyous clamor of her heart.
As soon as the city limits were reached, Graham stopped the car to telephone. It was after eleven o'clock, and there was little chance that George would have stayed at the phone so long, but he would leave a message for the early morning at least. George, however, had stuck to his post.
"Sure! I'm here yet! What'd ya think? Couldn't sleep, could I, with my sister off alone with a fella somewhere being kidnapped? What'd ya say? Found her? She's all right? Oh, gee! That's good! I told Carol you would! I told her not to worry! What'd ya say? Oh, Shirley's going to talk? Oh, hello, Shirley! How's Washington? Some speed, eh? Say, when ya coming home? To-morrow? That's good. No, mother doesn't know a thing. She thinks I went to bed early 'cause I planned to go fishing at sunrise. She went to bed herself early. Say, Mister Graham's a prince, isn't he? Well, I guess I'll go to bed now. I might make the fishing in the morning yet, if I don't sleep too late. I sure am glad you're all right! Well, so long, Shirley!"
