"Heavens above, man!" snapped Narkom. "It's as clear as crystal. I should apply for a warrant for her arrest immediately." "And yet, it was a revolver that had also been used, and one belonging to Sir Edgar. Miss Jennifer would hardly go so far as to murder the only obstacle that stood between the man she loved and his marriage to her rival. What, too, has become of that poor girl?" "Don't ask me, Cleek," returned the puzzled Superintendent, dolefully. "It's the most infernal riddle I ever came across, and my head's aching with it. I'm off to get additional help, if you don't mind, or else we shall have crowds surging into that room before we know where we are." "Right, Mr. Narkom, and as I still have a few threads to collect, Dollops and I will be off, too. We'll meet at the Hampton Arms. Come on, Dollops, we'll take a few impressions of those footprints before they're trodden out of existence to-morrow." "Righto, Guv'nor." Cleek took out his electric torch and the two set forth on their appointed task, leaving Mr. Narkom to set a sufficient guard over the silent figure of a dead man on whose face there rested an inscrutable smile. It was as if he were smiling over the secret he held and which was to puzzle many minds, and was one of the greatest riddles Cleek had ever attempted to solve. Meanwhile that gentleman and his zealous assistant worked silently and surely. Not a depressed blade of grass was left before it was subjected to the keenest scrutiny, while exact outlines were taken of the clearly defined footprints, with which the lawn was fairly alive. To recognize the unmistakable imprint of the Government Regulation boot worn by Mr. Narkom and Constable Roberts was a simple matter. The footprints of Cleek and Dollops were also distinguishable, for both had early in their companionship decided to wear boots which would always enable them to tell their own footprints from any they might be tracking, a precaution that had stood them in good stead on more than one occasion. It did so now, but even after having eliminated all the known ones there yet remained a bewildering number of marks, and a disgusted grunt broke from Dollops. "Lor' lumme, the place is alive with them, sir, and they're all about the same size. They're that young woman's or I'll eat my 'at!" But Cleek was silent, and as Dollops cautiously flashed his torch so that the light fell full upon his master's face, he gave a little start. Cleek was staring fixedly at the imprint of a newcomer, a man who had evidently come right up to a certain point, then stood still, as if waiting for something or someone to join him. "Lor', sir," said Dollops, looking down now in the same direction, "there's that girl's footmarks, too. They go down the lane side by side."
