Suggest me cozy mysteries with very less characters [Kind of : Agatha Christie books with less characters].

I love Agatha Christie’s books. But the issue is, her books have too many characters which makes it difficult to read and remember the name.

Her books having less characters, like, Five Little Pigs, are absolutely loved by me.

So please suggest cozy mysteries with less characters. Not necessarily from Golden Age of detective fiction period. Modern day books are also fine, but they should be light-hearted books \[it shouldn’t be too much focused on serious stuff like childhood abuse, rape or torturing someone etc\].
