July 25th, the Ballistics report reached Carella's desk. The shells and bullets found at the scene of Mike Reardon's death had been put beneath the comparison microscope together with the shells and bullets used in the killing of David Foster.
The Ballistics report stated that the same weapon had been used in both murders.
Chapter EIGHT
on the night that David Foster was killed, a careless mongrel searching for food in garbage cans had paused long enough to sully the sidewalk of the city. The dog had been careless, to be sure, and a human being had been just as careless, and there was a portion of a heelprint for the Lab boys to work over, solely because of this combined record of carelessness. The Lab boys turned to with something akin to distaste.
The heelprint was instantly photographed, not because the boys liked to play with cameras, but simply because they knew accidents frequently occurred in the making of a cast. The heelprint was placed on a black-stained cardboard scale, marked off in inches. The camera, supported above the print by a reversible tripod, the lens parallel to the print to avoid any false perspectives, clicked merrily away. Satisfied that the heelprint was now preserved for posterity—photographically, at least—the Lab boys turned to the less antiseptic task of making the cast.
One of the boys filled a rubber cup with half a pint of water. Then he spread plaster of Paris over the water, taking care not to stir it, allowing it to sink to the bottom of its own volition. He kept adding plaster of Paris until the water couldn't absorb anymore of it, until he'd dumped about ten ounces of it into the cup. Then he brought the cup to one of the other boys who was preparing the print to take the mixture.
Because the print was in a soft material, it was sprayed first with shellac and then with a thin coat of oil. The plaster of Paris mixture was stirred and then carefully applied to the prepared print. It was applied with a spoon in small portions. When the print was covered to a thickness of about one-third of an inch, the boys spread pieces of twine and sticks onto the plaster to reinforce it, taking care that the debris did not touch the bottom of the print and destroy its details. They then applied another coat of plaster to the print, and allowed the cast to harden. From time to time, they touched the plaster, feeling for warmth, knowing that warmth meant the cast was hardening.
Since there was only one print, and since it was not even a full print, and since it was impossible to get a Walking Picture from this single print, and since the formula

a formula designed to give the complete picture of a man's walk in terms of step length, breadth of step, length of left foot, right foot, greatest width of left foot, right foot, wear on heel and sole—since the formula could not be applied to a single print, the Lab boys did all they could with what they had.
And they decided, after careful study, that the heel was badly worn on the outside edge, a peculiarity which told them the man belonging to that heel undoubtedly walked with a somewhat duck-like waddle. They also decided that the heel was not the original heel of the shoe, that it was a rubber heel which had been put on during a repair job, and that the third nail from the shank side of the heel, on the left, had been bent when applying the new heel.
And—quite coincidentally if the heelprint happened to have been left by the murderer—the heel bore the clearly stamped trade name "O'Sullivan," and everyone knows that O'Sullivan is America's Number One Heel.
The joke was an old one. The Lab boys hardly laughed at all.
The newspapers were not laughing very much, either.
The newspapers were taking this business of cop-killing quite seriously. Two
