Sigma Rising. John Randolph Price

I think I remember a hedge on the side of the driveway."

      "I see it," Rigler said.

      "Get out of your car and wait for them there. When they leave the house, pop them. And I'm assuming you've chosen the proper weapon."

      "Yes sir, untraceable, ballistics meaningless, and I'm using a silencer."

      "I'll be waiting for your report."

      Agent Rigler slipped quietly out of the car, gun in hand. He was almost to the driveway when he heard two car doors closing. He crouched down behind the hedge, and when the engine started he rose and fired twice through the driver's side window. The street lamp provided sufficient light to see the driver slump over on the steering wheel. He then turned his gun to the passenger trying frantically to open the door on the other side, ample time for the agent to aim and spit lead through glass.

      Rigler looked around at the neighboring homes. No lights. All quiet. His boss would be pleased.
