The woman next door - Barbara Delinsky

On a charming cul-de-sac in suburban Connecticut, three-close knit couples find their long-cherished harmony undone when a lovely, younger neighbour, widowed a year ago and presumably still unattached, turns up pregnant.
Who is the father? Could it be one of the husbands? One by one, the couples turn inward, taking stock of their marriages and of the loyalties that perhaps have been taken too much for granted.
THE WOMAN NEXT DOOR is filled with suspense, and the kind of insights into her characters that have won Barbara Delinsky a loyal following.
