that these would-be murderers, whoever they are, whatever may be their mysterious motive, have grown desperate enough to invade the house itself has driven Lady Chepstow well-nigh frantic. Of course, orders were immediately given to the servants that no stranger, no matter how well dressed, how well seeming, nor what the plea, was, from that moment, to be allowed past the threshold. We felt secure in that, knowing that no servant of the household would betray his trust, and that all would be on the constant watch for any further attempt. The unknown enemy must have found out about these precautions, for no stranger came again to the door. But last night a thing we had never counted upon happened. In the dead of the night the unknown broke into the house, into the very nursery itself, and but that Lady Chepstow, impelled she does not know by what, rose and carried the sleeping child into her own bed, he would assuredly have been murdered. The nurse, awakened by a horrible suffocating sensation, opened her eyes to find a man bending over her with a chloroform-soaked cloth, which he was about to lay over her face. She shrieked and fainted, but not before she saw the man spring to the little bed on the other side of her own, hack furiously at it with a long, murderous knife, then dart to the window and vanish. In the darkness he had not, of course, been able to see that the child's bed was empty, for its position kept it in deep shadow, and hearing the household stir at the sound of the nurse's shriek, he struck out blindly and flew to save himself from detection. The nurse states that he was undoubtedly a foreigner – a dark-skinned Asiatic – and her description of him tallies with that Cedric gave of the man who attempted to kill him that day in the Park. There, Mr. Cleek," she concluded, "that's the whole story. Can't you do something to help us; something to lift this constant state of dread and to remove this terrible danger from little Lord Chepstow's life?"
"I'll try, Miss Lorne; but it is a most extraordinary case. Where is the boy now?"
"At home, closely guarded. We appealed to Mr. Narkom, and he generously appointed two detective officers to sit with him and keep constant watch over him whilst we are away."
"And in the meantime," added Mr. Narkom, "I've issued orders for a general rounding-up of all the Cingalese who can be traced or are known to be in town. Petrie and Hammond have that part of the job in hand, and if they hit upon any Asiatic who answers to the description of this murderous rascal – "
"I don't believe they will," interposed Cleek; "or, if they do, I don't for a moment believe he will turn out to be the guilty party. In other words, I have an idea that the fellow will prove to be a European."
"But, my dear fellow, both the boy and the nurse saw the man, and, as you have heard, they both agree that he was dark-skinned and quite Oriental in appearance."
"One of the easiest possible disguises, Mr. Narkom. A wig, a stick of grease-paint, a threepenny twist of crepe hair, and there you are! No, I do not believe that the man is a Cingalese at all; and, far from his having any connection with what you were pleased to term just now a change of front on the part of the Buddhists who have so long held the little chap as something sacred, I don't believe that they know anything about him. I base that upon the fact that the child is still treated with homage whenever he goes out, according to what Miss Lorne says, and that, with the single exception of that one woman who tried to poison him, nobody but one man – this particular one man – has ever made any attempt to harm the boy. Fanatics, like those Cingalese, cleave to an idea to the end, Mr. Narkom; they don't cast it aside and go off at another tangent. You have heard what Lady Chepstow says the native women told her: the boy was sacred; their priests had commanded them to appease Buddha by doing homage to him until the tooth was found, and the tooth has not been found up to the present day! That means that nothing on earth could change their attitude toward him, that not one of the Buddhist sect would harm a solitary hair of his head for a king's ransom; so you may eliminate the Cingalese from the case entirely so far as the attempts upon the child's life are concerned. Whoever is making the attempts is doing so without their knowledge and for a purely personal reason."
"Then, in that case, this Captain Hawksley – "
"I'll have a look at that gentleman before I tumble into bed to-night, and you shall have my views upon that point to-morrow morning, Mr. Narkom. Frankly, things point rather suspiciously in the captain's direction, since he is apparently the only person likely to be benefited by the boy's death, and if a motive cannot be traced to some other person – " He stopped abruptly and held up his hand. Outside in the dim halls of the house a sudden noise had sprung into being, the noise of some one running upstairs in great haste, and, stepping quickly to the door, Cleek drew it sharply open. As he did so, Dollops came puffing up out of the lower gloom, a sheep's trotter in one hand and a letter in the other.
"Law, guv'ner!" groaned he, from midway on the staircase, "I don't believe as I'm ever goin' to be let get a square tuck-in this side of the buryin' ground! Jist finished wot was left of that there steak and kidney puddin', sir, and started on my seckint trotter, when I sees a pair o' legs nip parst the area railin's to the front door, and then nip off again like greased lightnin', and when I ups and does a flyin' leap up the kitchen stairs, there was this here envellup in the letter-box and them there blessed legs nowheres in sight. I say, sir," agitatedly, "look wot's wrote on the envellup, will yer? And us always keepin' of it so dark."
Cleek plucked the letter from his extended hand, glanced at it, and puckered up his lips; then, with a gesture, he sent Dollops back below stairs, and, returning to the room, closed the door behind him.
"The enemy evidently knows all Lady Chepstow's movements, Mr. Narkom," he said. "I expect she and Miss Lorne have been under surveillance all day and have been followed here. Look at that!" He flung the letter down on a table as he spoke, and Narkom, glancing at it, saw printed in rude, illiterate letters upon the envelope the one word "Cleek." The identity of "Captain Burbage" was known to some one, and the secret of the house in Clarges Street was a secret no longer!
"Purposely disguised, you see. No one, not even a little child, would make such a botch of copying the alphabet as that," Cleek said, as he took the letter up and opened it. The sheet it contained was lettered in the same uncouth manner and bore these words:
"Cleek, take a fool's advice and don't accept the Chepstow case. Be warned. If you interfere, somebody you care about will pay the price. You'll find it more satisfactory to buy a wedding bouquet than a funeral wreath!"
"Oh!" shuddered the two ladies in one breath. "How horrible! How cowardly!" And then, feeling that her last hope had gone, Lady Chepstow broke into a fit of violent weeping and laid her head on Ailsa's shoulder.
"Oh, my baby! My darling baby boy!" she sobbed. "And now they are threatening somebody that you, too, love. Of course, Mr. Cleek, I can't expect you to risk the sacrifice of your own dear ones for the sake of me and mine, and so – and so – Oh, take me away, Miss Lorne! Let me go back to my baby and have him while I may."
"Good-night, Mr. Cleek," said Ailsa, stretching out a shaking hand to him. "Thank you so much for what you would have done but for this. And you were our last hope, too!"
"Why give it up then, Miss Lorne?" he said, holding her hand and looking into her eyes. "Why not go on letting me be your last hope – your only hope?"
"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,
