Deadly Beloved — Jane Haddam

DOWN THE AISLE -- TO DEATH
Armies on the eve of invasion could learn a thing or two about preparation from the denizens of Cavanaugh Street, who never do anything halfway. This time it's a wedding that's taking over the collective consciousness of the street-and bringing up painful memories for Gregor Demarkian. So when he's consulted on a murder in exclusive Fox Run Hill, the ex-FBI special agent is grateful for the diversion.

Why did country-club matron Patsy MacLaren Willis coldly shoot her husband in, his sleep? Why did she remove every trace of her existence from the home they'd shared, pipe bomb her own car -- and then disappear? The police think it's another marriage gone bad, but Demarkian thinks there's more to the case. And it soon looks like he's right: a second pipe bomb explodes, with devastating results, and Gregor knows that he must find a killer wedded to an explosive secret--before more victims take that final walk down the aisle.
