Looking for a Quick Transmigration Novel Where the Female Lead's First World Is a Murderous Maniac in a Rainstorm-Struck Villa

I forgot the heroine's name, but in the first world she's the wife of a man with a mental illness. Both her husband and his younger brother are in love with her. They go on vacation to somewhere like a villa or resort, then their car breaks down and they're trapped in a snowstorm, Agatha Christie-style. The heroine killed them all.
