There was a knock on the door. A patrolwoman stuck her head into the conference room. “Excuse me, but there’s a call for Navarro and Gillis.”

“I’ll take it,” said Gillis. He rose heavily to his feet and went to the conference wall phone.

Liddell was still focused on Sam. “So this is all that Portland’s finest can come up with? We wait for another bombing so that we can establish a pattern? And then maybe, just maybe, we’ll have an idea of what the hell we’re doing?”

“A bombing, Mr. Liddell,” said Sam calmly, “is an act of cowardice. It’s violence in the absence of the perpetrator. I repeat the word—absence. We have no ID, no fingerprints, no witnesses to the planting, no—”

“Chief,” cut in Gillis. He hung up the phone. “They’ve just reported another one.”

“What?” said Coopersmith.

Sam had already shot to his feet and was moving for the door.

“What was it this time?” called Liddell. “Another warehouse?”

“No,” said Gillis. “A church.”

THE COPS ALREADY had the area cordoned off by the time Sam and Gillis arrived at the Good Shepherd Church. A crowd was gathered up and down the street. Three patrol cars, two fire trucks and an ambulance were parked haphazardly along Forest Avenue. The bomb disposal truck and its boiler-shaped carrier in the flatbed stood idly near the church’s front entrance — or what was left of the front entrance. The door had been blown clear off its hinges and had come to rest at the bottom of the front steps. Broken glass was everywhere. The wind scattered torn pages of hymn books like dead leaves along the sidewalk. Gillis swore. “This was a big one.”

As they approached the police line, the officer in charge turned to them with a look of relief. “Navarro! Glad you could make it to the party.”

“Any casualties?” asked Sam.

“None, as far as we know. The church was unoccupied at the time. Pure luck. There was a wedding scheduled for two, but it was cancelled at the last minute.”
