Triple Threat by Jeffery Deaver

detective—O’Neil was his name—had her stay put so she could formally ID the sandy-haired guy. Oh, how she wanted to get the hell out of there. But she couldn’t arouse suspicion, so Harriet had cooled her heels, sucking down Diet Coke, and tried to wrestle with the anger and sorrow about her brother and Gabe.
    Then O’Neil and the poor bastard had returned. She’d IDed him with a fierce glance of warning and given them some fake information on how to reach her.
    And now she was in his car, heading back to the Dunes Inn.
    Oh, Wayne, I’ll miss you! Gabe, too.
    The motel loomed. She sped into the parking lot and braked to a stop.
    She was then aware of an odd vibration under her hands. The steering column. What was it?
    An earthquake?
    A problem with the car?
    She shut the engine off but the vibration grew louder.
    Leaves began to move and the dust swirled like a tornado in the parking lot.
    And Harriet understood. Oh, shit.”
    She pulled her Glock from her bag and sprinted toward the motel door, firing blindly at the helicopter as it landed in the parking lot. Several officers and, damn it, that detective, O’Neil, charged toward her. “Drop the weapon, drop the weapon!”
    She hesitated and laid the gun and her keychain on the ground. Then she dropped facedown beside them.
    Harriet was cuffed and pulled to her feet.
    O’Neil was approaching, his weapon drawn and looking for accomplices. A cluster of cops dressed like soldiers was slowly moving toward the motel room.
    “Anyone in there?” he asked.
    “No.”
    “It was just the three of you?”
    “Yes.”
    The detective called, “Treat it dynamic in any case.”
    “How’d you know?” she snapped.
    He looked her over neutrally. “The cargo pants.”
    “What?”
    “You described the man in the car and said one was wearing cargo pants. You couldn’t see the pants of somebody inside a car from sixty feet away. The angle was wrong.”
    Hell, Harriet thought. Never even occurred to her.
    O’Neil added that the man they’d believed was one of the conspirators was acting too nervous. “It occurred to me that he might’ve been set up. He told me what you’d done. We tracked his car here with his GPS.” O’Neil was going through her purse. “You’re his sister, Wayne’s.”
    “I’m not saying anything else.” Harriet was distracted, her eyes taking in the motel room.
    O’Neil caught it and frowned. He glanced down at her keychain, which held both a fob for her car and the second one.
    She caught his eye and smiled.
    “IED in the room!” he called. “Everybody back! Now.”
    It wasn’t an explosive device, just a gas bomb Gabe had rigged in the event something like this happened. It had been burning for three minutes or so—she’d pushed the remote control the second she’d seen the chopper—but the smoke and flames weren’t yet visible.
    Then a bubble of fire burst through two of the windows.
    Armed with extinguishers, the tactical team hurried inside to salvage what they could, then retreated as the flames swelled. One officer called, “Michael! We spotted a box of plastic explosive detonators, some timers.”
    Another officer ran up to O’Neil and showed him what was left of a dozen scorched documents. They were the floor plan for the site of the attack at the CCCBA party. He studied it. “A room with a stage. Could be anywhere. A corporation, school, hotel, restaurant.” He sighed.
    Harriet panicked, then relaxed, as she snuck a glimpse and noted that the name of the motel was on a part of the sheet that had burned to ash.
    “Where is this?” O’Neil asked her bluntly.
    Harriet studied it for a moment and shook her head. “I’ve never seen that before. You planted it to incriminate me. The government does that all the time.”
