Point and click from childhood

Hello,

I have looked desperately for this game without a lot I can remember of it.

What I remember (it is really not much), it was a point and click game, there was at least a murder or one was trying to solve a murder, I remember at one point I was in a garden and a small house (more like the toilets house outside of the old American movies) was on the back, I remember opening a door and that inside it was radial colors as if the screen was filled with several triangles of different colors connected on the center. Also at one point there was a cow. I remember also that for that time I found it scary, I was around 12.Maybe we were a detective?. It is all I can remember yes I am sorry it is almost nothing. This was in the end of the 90s beginning of 2000s

On the other side, I remember other games I had (I remember them because as I was not scary I played more). In the same computer I had

Freddie the fish

Putt putt the car

Castel of the winds

Street road 1

Anno 1810

Loom

Maybe a little bit later rage of mage

I know I am asking too much with too little information but I have even watched full videos of all point and click pc games on YouTube trying to find if something rings me a bell, without any luck. Also tried ai but with so little information and a lot of I guess, impossible to find something... This fade memory of this game had came and go several times in my life and I always wanted to know which one it was.
