“He didn’t even touch the guy’s hands in there. So you better wait until the cut before you go saying something you aren’t sure about.”

Sakai finished transferring the fingerprints and then handed the card to Bosch.

“Bag the hands,” Bosch said to him, though he didn’t need to. “And the feet.”

He stood back up and began waving the card to get the ink to dry. With his other hand he held up the plastic evidence bag Sakai had given him. In it a rubber band held together a hypodermic needle, a small vial that was half filled with what looked like dirty water, a wad of cotton and a pack of matches. It was a shooter’s kit and it looked fairly new. The spike was clean, with no sign of corrosion. The cotton, Bosch guessed, had only been used as a strainer once or twice. There were tiny whitish-brown crystals in the fibers. By turning the bag he could look inside each side of the matchbook and see only two matches missing.

Donovan crawled out of the pipe at that moment. He was wearing a miner’s helmet equipped with a flashlight. In one hand he carried several plastic bags, each containing a yellowed newspaper, or a food wrapper or a crushed beer can. In the other he carried a clipboard on which he had diagramed where each item had been found in the pipe. Spiderwebs hung off the sides of the helmet. Sweat was running down his face and staining the painter’s breathing mask he wore over his mouth and nose. Bosch held up the bag containing the shooter’s kit. Donovan stopped in his tracks.

“You find a stove in there?” Bosch asked.

“Shit, he’s a hype?” Donovan said. “I knew it. What the fuck are we doin’ all this for?”

Bosch didn’t answer. He waited him out.

“Answer is yes, I found a Coke can,” Donovan said.

The crime scene tech looked through the plastic bags in his hands and held one up to Bosch. It contained two halves of a Coke can. The can looked reasonably new and had been cut in half with a knife. The bottom half had been inverted and its concave surface used as a pan to cook heroin and water. A stove. Most hypes no longer used spoons. Carrying a spoon was probable cause for arrest. Cans were easy to come by, easy to handle and disposable.
