Always, when staying at the cottage alone, Cleek's disguise was that of "Cap'n Burbage," guardian of his ward, Ailsa Lorne. Mrs. Condiment, the housekeeper, therefore, greeted the "Cap'n" heartily on the threshold of the cottage when he arrived. Ailsa was for the present in safe hands—on a visit with Mrs. Narkom. Secure, therefore, in his "Cap'n Burbage" disguise, Cleek went to and fro, with peace and serenity restored to his soul. So determined was he to have these few days undisturbed that in spite of his affection for Mr. Narkom, he instructed Mrs. Condiment to say, in answer to any telephone calls, that he was not at the cottage.

Mr. Narkom, seated in his office at the Yard, a few days later, flung aside the pen with which he had been beating an idle tattoo, thus showing the tension and anxiety under which he was almost unbearably labouring, and wheeled round in his chair. He heard the sound of footsteps, telling him that his trusted messenger, Hammond, was returning at last. He gave vent to a little sigh of relief. Now he would know what had really happened, and be able to prove to a waiting public and sneering newspapers that Scotland Yard was not "asleep," but that neither was it to be bullied nor cajoled into blurting out all that it knew. "Gad," he ejaculated, mentally, wouldn't he like to have some of those brilliant young cub reporters have his job for a week, and let them see if they could fathom mysteries, such as were searing his forehead at the present moment, any quicker than he himself.

The door opened and shut, and Detective-Sergeant Hammond was stepping briskly across the room.

"Well?" rapped out the Superintendent in a sharp staccato born of nervous impatience. "A false alarm, wasn't it?"

"No, sir, it's not. It's the greater part of Tooting Common this time—sheep blown to bits and a few kiddies, too, I'm afraid. I was just in time to see a second explosion myself, as I got there—that's the seventh one altogether, and heaven knows what's the cause or reason. And where will the next one be? The papers will be raving over this to-night."

"Can't rave more than they've done now. I'd give my head to make those beastly reporters sit up!"

"There's only one man to help you, sir, beggin' yer pardon." Hammond dropped his voice almost to a whisper. "That's Mr. Cleek——"

"Do you think I don't know that?" Narkom snapped back, impatiently. "Do you think I'd have waited till now if I'd known where he was? I've done nothing but ring that confounded 'phone day in and day out and all I get is that 'Captain Burbage is away.' Captain Burbage, indeed! To think that after all these years we can't protect him against those devils of Apaches without his living in this constant disguise."

"'Tisn't like Mr. Cleek to be long away from the Yard, either," said Hammond, scratching his head reflectively.
