There came an odd whizzing sound from up the pavement. Mallory glanced in that direction and saw a queer half-crouching ghostly figure emerge from the fog, clothing flapping about it with speed, a pair of walking-canes doubled up under its arms.
Mallory jumped back at the last possible instant as the boy shot past him with a yowling whoop. A London boy, thirteen or so, on rubber-wheeled boots. The boy turned swiftly, skidded to an expert stop, and began to pole himself back up the pavement
with the walking-sticks. Presently, an entire pack of boys had surrounded Mallory and Fraser, leaping and yelping in devilish glee. None of the others had wheeled shoes, but nearly all wore the little square cloth masks that Bureau clerks donned to tend their Engines.
"Say, you lads!" Fraser barked, "where did you get those masks?"
They ignored him. "That was dead flash!" one of them shouted. "Do it again. Bill!" Another boy cocked his leg three times with an odd ritual motion, then jumped high in the air and crowed "Sugar!" Those around him laughed and cheered.
"Calm down, you," Fraser ordered.
"Vinegar phiz!" a wicked boy fleered at him. "Shocking bad hat!" The whole pack of them burst into raucous hilarity.
"Where are your parents?" Fraser demanded. "You shouldn't be running about in this weather."
"Nuts and knuckles!" sneered the boy in wheeled shoes. "Forward all, my hearty crew! Panther Bill commands!" He jabbed his walking-sticks down and off. The others followed, yelling and whooping.
"Far too well-dressed to be street-arabs," Mallory remarked.
The boys had run off a short distance and were setting up for a game of crack-the-whip. Swiftly, each boy grabbed the next by the arm, forming a chain. The boy on wheels took the tail-end.
"Don't like the look of that," Mallory muttered.
The chain of boys swung out across Camera Square, each link gathering impetus, and suddenly the wheel-footed boy shot loose from the end like a stone from a catapult. He skidded off with a scream of devilish glee, hit some small discontinuity in the pavement, and tripped headlong into a sheet of plate-glass.
Shards of glass burst from the store-front, toppling like guillotine blades.
Young Panther Bill lay upon the pavement, seemingly stunned or dead. There was an awful moment of shocked silence.
"Treasure!" shrilled one of the boys. With maddened shrieks, the pack scrambled for the broken store-front and began grabbing every display-item in sight: telescopes, tripods, chemical glassware
"Halt!" Fraser shouted. "Police!" He reached inside his coat, yanked his kerchief down, and sounded three sharp blasts on a nickel-plate police-whistle.
The boys fled instantly. A few dropped their snatched booty, but the rest clutched their prizes fiercely and ran like Barbary apes. Fraser hoofed it after them, Mallory at his heels, reaching the store-front where Panther Bill still lay sprawled. As they approached, the boy levered himself up on his elbow and shook his bleeding head.
"You're hurt, son," Mallory said.
"I'm right and fly!" said Panther Bill sluggishly. His scalp was slashed to the bone and blood was pouring over both his ears. "Hands off me, you masked bandits!"
Belatedly, Mallory pulled his own kerchief down and tried to smile at the boy. "You're injured, son. You need help." Together with Fraser, he bent over the boy.
"Help!" the boy screeched. "Help me, my crew!"
Mallory turned to look. Perhaps one of the other boys could be sent for aid.
A glittering triangular shard of flung glass spun from the fog, catching Fraser square in the back. The policeman jerked upright with a look of wide-eyed animal shock.
Panther Bill scrambled off on his hands and knees and jumped to his skidding feet. There was a loud smash from another store-front nearby, the musical clatter of glass, and delighted screams.
The glass-shard protruded in shocking fashion from Fraser's back. It was imbedded in him. "They're going to kill us!" Mallory cried, hauling Fraser along by the arm. Behind them glass was bursting like bombs, some of it flung blindly to shatter against the walls, some cascading from its shop-front mullions.
"Bloody hell," Fraser muttered.
Panther Bill's cry rang through the fog. "Treasure, my hearties! Treasure!"
"Clench your teeth," Mallory said. Folding his kerchief to protect his hand, he plucked the shard from Fraser's back. To his great relief, it came out of a piece. Fraser shuddered.
Mallory helped him gently out of his coat. Gore had streaked Fraser's shirt to the waistline, though it seemed not as bad as it might have been. The glass-shard had stabbed the chamois-leather strap of Fraser's shoulder-holster, which held a stout little pepperbox. "Your holster stopped most of it," Mallory said. "You're cut, but it's not deep, not through the ribs. We need to staunch that bleeding "
"Police station," Fraser nodded, "Kings Road West." He had gone very pale.
A fresh cascade of smashing glass echoed distantly behind them.
