"Yes, but they—they spoke of a funeral wreath."
"And they also spoke of a wedding bouquet! I am going to take the case, Miss Lorne—take it, and solve it, as I'm a living man. Thank you!" as her brimming eyes uplifted in deep thankfulness and her shaking hand
returned the pressure of his. "Now, just give me five minutes' time in the next room—it's my laboratory, Lady Chepstow—and I'll tell you whether I shall begin with Captain Hawksley or eliminate him from the case entirely. You might go in ahead, Mr. Narkom, and get the acid bath and the powder ready for me. We'll see what the finger-prints of our gentle correspondent have to tell, and, if they are not in the records of Scotland Yard or down in my own private little book, we'll get a sample of Captain Hawksley's in the morning."
Then, excusing himself to the ladies, he passed into the inner room in company with Narkom, and carried the letter with him. When he returned it was still in his hand, but there were grayish smudges all over it.
"There's not a finger-print in the lot that is worth anything as a means of identification, Miss Lorne," he said. "But you and Lady Chepstow may accept my assurance that Captain Hawksley is not the man. The writer of this letter belongs to the criminal classes; he is on his guard against the danger of finger-prints, and he wore rubber gloves when he penned this message. When I find him, rest assured I shall find a man who has had dealings with the police before and whose finger-prints are on their records. I don't know what his game is nor what he's after yet, but I will inside of a week. I've an idea; but it's so wild a thing I'm almost afraid to trust myself to believe it possible until I stumble over something that points the same way. Now, go home with Lady Chepstow, and begin the work of helping me."
"Helping you? Oh, Mr. Cleek, can we? Is there anything we can do to help?"
"Yes. When you leave the house, act as though you are in the utmost state of dejection, and keep that up indefinitely. Make it appear, for I am certain you will be followed and spied upon, as if I had declined the case.
But don't have any fear about the boy. The two constables will sleep in the room with him to-night and every night until the thing is cleared up and the danger past. To-morrow about dusk, however, you, personally, take him for a walk near the Park, and if, among the other Cingalese you may meet, you should see one dressed as an Englishman, and wearing a scarlet flower in his buttonhole, take no notice of how often you see him nor of what he may do."
"It will be you, Mr. Cleek?"
"Yes. Now go, please; and don't forget to act as if you and her ladyship were utterly broken-hearted. Also"—his voice dropped lower, his hand met her hand, and in the darkness of the hall a little silver-plated revolver was slipped into her palm—"also, take this. Keep it always with you, never be without it night or day, and if any living creature offers you violence, shoot him down as you would a mad dog. Good-night, and—remember!"
