Sachs said, “The Composer isn’t a serial killer.”

Ercole nodded. “No, he hasn’t killed, that’s true. You saved the victim. And we have not found the abducted man’s body here.”

Rossi: “Detective Sachs doesn’t mean that, Ercole.”

“No, Inspector, you’re right. A serial killer is a rare and specific criminal profile. In males the motives’re sexual in nature usually, or nonsexual sadism. And while there’s ritualistic behavior, that’s limited in most cases to binding or arranging the victims in certain ways or leaving fetishes at the scene or taking trophies, postmortem. The behavior doesn’t rise to the Composer’s level of elaborate staging—the videos, the noose, the music. He’s a multiple perpetrator.”

Silence flowed into the room. Then Rossi spoke. “We thank you for your insights and assistance.”

“In whatever humble way we can,” Rhyme said. Not very humbly.

“And in coming all this way to deliver to us that file.” Not very subtly.

Then Rossi looked him over. “You, Captain Rhyme, I think, are not used to perpetrators, come si dice? Absconsioning?”

“Absconding,” Ercole corrected his boss. Then froze, blushing once more.

“No, I am not,” Rhyme said. Dramatically, perhaps overly so. Though he believed the delivery was appropriate since his impression was that Rossi, too, was a cop who would not do well with absconsioning perpetrators.

“You are hoping for extradition,” Rossi said. “After we catch him.”

“I hadn’t thought that far,” Rhyme lied.

“No?” Rossi brushed at his mustache. “Whether the trial is here or in America, that is a decision for the court, not for me or for you. Allora, I appreciate what you’ve done, Captain Rhyme. The effort. It must be taxing.” He avoided a glance at the wheelchair. “But now you have delivered your report I cannot see how you can be of further help. You are a crime scene expert but we have crime scene experts here.”

“Your Scientific Police.”

“Ah, you know of them?”

“I lectured at the main facility in Rome years ago.”

“I do hate to disappoint you, and you, as well, Signorina Sachs. But, once again, I see little you can offer other than that.” He nodded to her bag. “And there are practical issues. Officer Benelli and I speak serviceable English but most others involved in the case do not. I must add too that Naples is not a very…” He sought a word. “…accessible city. For someone like you.”

“I’ve noticed.” Rhyme shrugged, a gesture he was fully capable of.

Silence, again.

Broken at last by Rhyme: “Translation is easy, thanks to Google. And regarding mobility: In New York, I don’t get out to crime scenes much. No need. I leave that to my Sachs and other officers. They return like bees with nectar. And we concoct the honey together. Forgive the metaphor. But what can it possibly hurt, Inspector, for us to hang around? We’ll be sounding boards for ideas.”

“Sounding board” seemed to confuse him.

Ercole translated.

Rossi paused then said, “This that you are proposing, it is irregular and we are not people who are well with irregularness.”
