Head cocked to one side, tulip ears alert, Laddie stood listening. To the keenest human ears the thief's soft progress across the wide living room to the wall-safe would have been all but inaudible. But Lad could follow every phase of it; the cautious skirting of each chair; the hesitant pause as a bit of ancient furniture creaked; the halt in front of the safe; the queer grinding noise, muffled but persevering, at the lock; then the faint creak of the swinging iron door, and the deft groping of fingers. Soon, the man started back toward the pale oblong of gloom which marked the window's outlines from the surrounding black. Lad's tail began to wag again. Apparently, this eccentric person was coming out, after all, to keep him company. Now, the man was kneeling on the window-seat. Now, in gingerly fashion, he reached forward and set the small bag down on the veranda; before negotiating the climb across the broad seat,--a climb that might well call for the use of both his hands. Lad was entranced. Here was a game he understood. Thus, more than once, had the Mistress tossed out to him his flannel doll, as he had stood in pathetic invitation on the porch, looking in at her as she read or talked. She had laughed at his wild tossings and other maltreatments of the limp doll. He had felt he was scoring a real hit. And this hit he decided to repeat. Snatching up the swollen little satchel, almost before it left the intruder's hand, Lad shook it, joyously, reveling in the faint clink and jingle of the contents. He backed playfully away; the bag-handle swinging in his jaws. Crouching low, he wagged his tail in ardent invitation to the stranger to chase him and get back the satchel. Thus did the Master romp with Lad, when the flannel doll was the prize of their game. And Lad loved such races. Yes, the stranger was accepting the invitation. The moment he had crawled out on the veranda he reached down for the bag. As it was not where he thought he had left it, he swung his groping hand forward in a half-circle, his fingers sweeping the floor. Make that enticing motion, directly in front of a playful collie pup; specially if he has something he doesn't want you to take from him;--and watch the effect. Instantly, Lad was athrill with the spirit of the game. In one scurrying backward jump, he was off the veranda and on the lawn, tail vibrating, eyes dancing; satchel held tantalizingly towards its would-be possessor. The light sound of his body touching ground reached the man. Reasoning that the sweep of his own arm had somehow knocked the bag off the porch, he ventured off the edge of the veranda and flashed a swathed ray of his pocket light along the ground in search of it.
