The smoking station.

Sachs supposed that, unable to smoke indoors many places in Italy, nicotine addicts would migrate to places like this: decks and patios. The view was spectacular. You could see the entire expanse of Naples Bay, the misty form of the volcano to one side and, to the other, a massive castle, which was nearby.

Sachs walked from the smoking station around the corner of one of the sheds, secluded from view. There was a bench here, where Garry and Frieda would have settled in for their limonarono—or whatever the gerund of that verb might be.

Natalia said, in a weak voice, “The attack occurred over there.” She pointed to the roof of the adjoining building, delineated by yellow police tape. “I will never look at this place again the same way. So pleasant once. And now, so terrible.”

They walked to the tape. There was no gap between this building and the one next door; they were separated only by a brick wall, about three feet high. Looking left, Sachs and Ercole could see another cordoned-off area of police tape on the adjoining structure, where the actual crime had occurred. This was out of sight of the smoking station. A logical place for an attack.

“Let’s go.”

“But the tape!” Ercole whispered.

She smiled at him. Mindful of her joints, Sachs sat on the wall and eased onto the neighboring roof. Ercole sighed then leapt over. Natalia remained on the roof of her building. The pebbles covering the tar paper meant that they could find no footprints, so they didn’t worry about booties or rubber bands. Pulling on latex gloves, Sachs took samples of the stones and flecks of tar from the place where the assault had occurred and the route leading to it.

When she was finished, she looked across the street and to the south at a tall building a half block away.

“What is that?”

Ercole noted the modern high-rise. “A hotel. The NV, I believe. A very nice place.”

She squinted into the sun. “It looks like that’s a parking garage.”

“Yes, I think so.”

“About level with the roof here. Let’s find out if they have a CCTV, and if it’s pointed this way.”

“Yes, yes, good. Many parking structures have video security. I’ll follow up on that.”

She nodded and they returned to the smoking station and she performed a similar evidence collection there, as Natalia watched with curiosity. “It is like that show CSI. Isn’t it?”

“Very much like that,” Sachs said.

In ten minutes they were finished. Sachs and Ercole thanked the young woman. She shook their hands firmly and opened the door for them to leave. “Please, I am sure Garry could not have done this. In my heart I know.” Her eyes darkened and she glanced in the direction of the building next door. “Those men, those Serbians, you should look once more at them. I read people very good. I do not trust them at all.”
