Children swarmed the street and gathered at corners. The older ones played boldly in midstreet, while the toddlers invented games that kept them to the sidewalk and curb. The policeman came stealthily upon one of these latter groups--Italians. At the sight of his brass buttons they fled precipitately. He laughed. Once in a month of moons he was able to get near enough to touch them. Natural. Hadn't he himself hiked in the old days at the sight of a copper? Sure, he had. A bit of colour on the sidewalk attracted his eye, and he picked up the object. Something those kids had been playing with. A bit of red glass out of a piece of cheap jewellery. Not half bad for a fake. He would put one over on Maggie when he turned in for supper. Certainly this was the age of imitation. You couldn't buy a brass button with any confidence. He put the trinket in his pocket and continued on, soon to forget it. At six he was off duty. As he was leaving the precinct the desk sergeant called him back. “Got change for a dollar, an' I'll settle that pinochle debt,” offered the sergeant. “I'll take a look.” The policeman emptied his coin pocket. “What's that yuh got there?” “Which?” “The red stone?” “Oh, that? Picked it up on the sidewalk. Some Italian kids dropped it as they skedaddled.” “Let's have a look.” “Sure.” The policeman passed over the stone. “Gee! That looks like real money. Say, they can do anything with glass these days.” “They sure can.” A man in civilian clothes--a detective from headquarters--went up to the desk. “What you guys got there?” “A ruby this boob picks up off'n the sidewalk,” said the sergeant, winking at the finder, who grinned. “Let's have a squint at it.” The stone was handed to him. The detective stared at it carefully, holding it on his palm and rocking it gently under the desk light. Crimson darts of flame answered to this treatment. He pushed back his hat. “Well, you boobs!” he drawled. “What's the matter?” “Matter? Why, this is a ruby! A whale of a ruby, an' pigeon blood at that! I didn't work in the' appraiser's office for nothing. But for a broken point--kids probably tried to crack it--it would stack up somewhere between three and four thousand dollars!” The sergeant and the policemen barked simultaneously: “What?” “A pigeon blood. Where was it you found it?” “Holy Moses! On Eightieth.” “Any chance of finding that bunch of kids?” “Not a chance, not a chance! If I got the hull district here there wouldn't be nothin' doin'. The kids'd be too scared t' remember anything. A pigeon-blood ruby, an' I wasn't gonna pick it up at first!” “Lock it up, sergeant,” ordered the detective. “I'll pass the word to headquarters. Too big for a ring. Probably fallen from a pin. But there'll be a holler in a few hours. Lost or stolen, there'll be some big noise. You two boobs!” “Well, whadda yuh know about that?” whined the policeman. “An' me thinkin' it was glass!”
