A

Navy petty officer first-class dies of a single shot in Rock Creek Park, Washington, DC; Gibbs and company investigate; Gibbs says that the weapon is 7 m.m. and maybe a high-powered sniper rifle; witnesses describe a strange event. Hollis Mann, a retired Army lieutenant colonel and a lady from Gibbs's background, reappears; for the DoD she has investigated a contractor connected to the current case; she names one suspect (Erin, a woman software engineer); while on a stakeout for a second suspect, Gibbs and Mann find, rescue, and interview Erin, then arrest her. An explosion damages a hotel, routs a gala award-presentation dinner, kills six people, and injures 22, including Delilah, McGee's girlfriend, who undergoes surgery to repair her injuries from shrapnel. Tony and Ellie provide the location of the bad guys to Gibbs and Mann, who pursue; they zap two underlings, but the ringleader slips away. [To be continued.]
