It reminds me of The Three-Body Problem novel/series. At the beginning, the police is investigating on multiple suicides by scientists.

It reminds me of the plot of Alternative 3 where the scientists aren't disappearing, they're moving to Mars.

I think its a fairly common plot. Its also the plot of So many steps to death by Agatha Christie.
