SOLVED. General Fiction. Mother kills Father and won’t explain why. [s]

[Meg]

Father is a serial cheater, 3 adult daughters all have difficult relationships with their husbands. Their good friend turns up to be sleeping with dead Father, after her mother slept with the dead Father. You can guess where this was going... Mother shot the Father for his incestuous relationships!

[Meg]

Still looking for this.

The cover (about 15 years ago) was white with soft blues and pinks, a very girly cover, with no people on it.

Where and when is it set?
Literary fiction or mass market fiction?

[Meg]

Mass market fiction.

Found it! Was reading a review of a bad Kristin Hannah book comparing to Eileen Goudge books! Ding Ding Ding!
