Detective Sergeant Fitzgerald had his revolver out. He drew in his breath for a stentorian command for them to drop their weapons. But he didn't have time to shout. The hurtling small box of spot-remover struck the large sheet-iron case from which loud rumblings came. It was a dryer; a device for spinning clothes which were wet with liquid from the dry-cleaning washer. A perforated drum revolved at high speed within it. The box of spot-remover hit the door. The door dented in, hit the high-speed drum inside, and flew frantically out again, free from its hinges and turning end-for-end as it flew. It slammed into the thrower's companion, spraining three fingers as it knocked his revolver to the floor. The weapon slid merrily away to the outer office between Detective Fitzgerald's feet.
But this was not all. The dryer-door, having disposed of one threatening revolver, slammed violently against the wall. The wall was merely a thin partition, neatly paneled on the office side, but with shelves containing cleaning-and-dyeing supplies on the other. The impact shook the partition. Dust fell from the shelves and supplies. The hood who hadn't lost his gun sneezed so violently that his hat came off. He bent nearly double, and in the act he jarred the partition again.
Things fell from it. Many things. A two-gallon jar of extra-special detergent, used only for laces, conked him and smashed on the floor before him. It added to the stream of fluid already flowing with singular directness for the open, double, back-door of the workroom. The hood staggered, sneezed again, and convulsively pulled the trigger of his gun. The bullet hit something which was solid heavy metal, ricocheted, ricocheted again and the second hood howled and leaped wildly into the air. He came down in the flowing flood of spilled detergent, flat on his stomach, and with marked forward momentum. He slid. The floor of the plant had recently been oiled to keep down dust. The coefficient of friction of a really good detergent on top of floor-oil is remarkably low,—somewhere around point oh-oh-nine. Hood number two slid magnificently on his belly on the superb lubrication afforded by detergent on top of floor-oil.
The first hood staggered. Something else fell from the shelf. It was a carton of electric-light bulbs. Despite the protecting carton, they went off with crackings like gunfire. Technically, they did not explode but implode, but the hood with the revolver did not notice the difference. He leaped—and also landed in the middle of the wide streak of detergent-over-oil which might have been arranged to receive him.
He remained erect, but he slid slowly along that shining path. His relatively low speed was not his fault, because he went through all the motions of frenzied flight. His legs twinkled as he ran. But his feet slid backward. He moved with a sort of dignified celerity, running fast enough for ten times the speed, upon a surface which had a frictional coefficient far below that of the smoothest possible ice.
Detective Sergeant Fitzgerald gaped, his mouth dropped open and his gun held laxly in a practically nerveless hand.
The thing developed splendidly. The prone gunman slid out of the wide double door, pushing a bow-wave of detergent before him. He slid across the cement just outside, into the open garage whose delivery-truck was absent, and slammed with a sort of deliberate violence into a stack of four cardboard drums of that bone-black which is used to filter cleaning-fluid so it can be used over again in the dry-cleaning machine. The garage was used for storage as well as shelter for the establishment's truck.
The four drums were not accurately piled. They were three and a half feet high and two feet in diameter. They toppled sedately, falling with a fine precision upon the now hatless, running, sliding hood. One of them burst upon him. A second burst upon the prone man—who had butted through the cardboard of the bottom one on his arrival. There was a dense black cloud which filled all the interior of the garage. It was bone-black, which cannot be told from lamp-black or soot by the uninitiated.
From the cloud came a despairing revolver shot. It was pure reflex action by a man who had been whammed over the head by a hundred-and-fifty-pound drum of yielding—in fact bursting—material. There was a metallic clang. Then silence.
In a very little while the dust-cloud cleared. One figure struggled insanely. Upon him descended—from an oil drum of cylinder-oil stored above the rafters—a tranquil, glistening rod of opalescent cylinder-oil. His last bullet had punctured the drum. Oil turned the bone-black upon him into a thick, sticky goo which instantly gathered more bone-black to become thicker, stickier, and gooier. He fought it, while his unconscious companion lay with his head in a crumpled cardboard container of more black stuff.
