It was that of a dapper and thin-faced man who might have been anywhere from forty to sixty years of age. He walked, however, with a quick and nervous step. Yet the most remarkable thing about him seemed to be his eyes. They were wide-set and protuberant, like a bird’s, as though years of being hunted had equipped him with the animal-like faculty of determining without actually looking back just who might be following him.

Those alert and wide-set eyes, in fact, must have sighted McCooey at the same time that he fell under the vision of the old cement seller. For the dapper figure wheeled quietly and quickly about and stooped down at the very side of the humming patrolman. He stooped and examined one of the peddler’s many-fractured china plates. He squinted down at it as though it were a thing of intense interest to him.

As he stooped there the humming patrolman was the witness of a remarkable and inexplicable occurrence. From the throat of the huge-shouldered peddler, not two paces away from him, he heard come a hoarse and brutish cry, a cry strangely like the bawl and groan of a branded range-cow. At the same moment the gigantic green-draped figure exploded into sudden activity. He seemed to catapult out at the stooping dapper figure, bearing it to the sidewalk with the sheer weight of his unprovoked assault.

There the struggle continued. There the two strangely diverse bodies twisted and panted and writhed. There the startlingly agile dapper figure struggled to throw off his captor. The arch of gas-pipe went over. Glue-bottles showered amid the shattered glass and crockery. But that once placid-eyed old cement seller stuck to the unoffending man he had so promptly and so gratuitously attacked, stuck to him as though he had been glued there with his own cement. And before the patrolman could tug the combatants apart, or even wedge an arm into the fight, the exulting green-coated figure had his enemy on his back along the curb, and, reaching down into his capacious pocket, drew out two oddly shaped steel wristlets. Forcing up his captive’s arm, he promptly snapped one steel wring on his own wrist, and one on the wrist of the still prostrate man.

“What’re yuh tryin’ to do?” demanded the amazed officer, still tugging at the great figure holding down the smaller man. In the encounter between those two embattled enemies had lurked an intensity of passion which he could not understand, which seemed strangely akin to insanity itself.

It was only when McCooey pushed his way in through the crowd and put a hand on his shoulder that the old cement seller slowly rose to his feet. He was still panting and blowing. But as he lifted his face up to the sky his body rumbled with a Jove-like sound that was not altogether a cough of lungs overtaxed nor altogether a laugh of triumph.

“I got him!” he gasped.

About his once placid old eyes, which the hardened tear-ducts no longer seemed able to drain of their moisture, was a look of exultation that made the gathering street-crowd take him for a panhandler gone mad with hunger.

“Yuh got who?” cried the indignant young officer, wheeling the bigger man about on his feet. As the cement seller, responding to that tug, pivoted about, it was noticeable that the man to whom his wrist was locked by the band of steel duly duplicated the movement. He moved when the other moved; he drew aside when the other drew aside, as though they were now two parts of one organism.

“I got him!” calmly repeated the old street-peddler.
