Agatha Christie's Partners in Crime

I watched this movie and three episodes. Very funny detectives. Like it.

In A. Christie's first work, they are under 20 years old, in the last they are already under 70.

It doesn't happen that way. Ancient old women who are about to go to their graves themselves don't kill a crowd of people to get an inheritance. It doesn't make sense anymore. I should have moved earlier.)))

The characters in the books were between 20-25, in the film they call each other young, but the actors are 35-40:(
