"That's a good name if they do what I think," Hardy said.

"It's a fine name," Glitsky agreed. He knew, although the police department would deny it as a matter of course, that no hit-and-run incidents-even the homicides-were more than cursorily investigated by inspectors. What usually happened was that a couple of members of the hitand-run detail would take the paperwork at the Hall of Justice the day after the incident. Maybe they would go to the scene of an accident and see if they could find a witness to provide a description or license number of the vehicle. If that failed, and there were no good eyewitnesses in the report, that was essentially the end of the investigation. If they had a license number, they punched it into their computers to see if they had a street address associated with the vehicle. Sometimes, if the accident got a lot of press and they had a vehicle description, they would call a body shop or two and see if any cars matching the hit-and-run vehicle had surfaced. Usually the answer was no. "It's a fine department, even. But it doesn't do what we do, which is investigate murders."

"In spite of your detail's name, which indicates an interest in all homicides."

"Hence the confusion," Glitsky said. "Some of our civic leaders remain unclear on the concept."

They walked in silence for another moment. "What's second?" Hardy asked.

"What's second what?"

"You said you don't investigate hit-and-run homicides, first, because there's a separate hit-and-run detail. When you say first, it implies there's a second."

Glitsky's pace slackened; then both men stopped. "Second is that hit-and-run homicides tend not to be murders. In fact, they're never murders."

"Never say never."

"This time you can. You want to know why?"

"It's hard to ditch the murder weapon?"
