I'm jumping in late, but for my take on the "Murder, They Wrote" theme, I'll nominate a title by Sarah Caudwell (pen name for Sarah Cockburn), in which telexes play a big role. (This is not a spoiler...) Hence - "Murder, They Wrote" - or at least - "Murder, They Telexed".
Anyway, the book I'm suggesting is the third in Caudwell's woefully-too-short four book series,
The Sirens Sang of Murder.
I would have liked to propose the first book in the series,
Thus Was Adonis Murdered, since some folks like to read in order, but it doesn't seem to be available in the US. So I'm going with
Sirens, which did, BTW, win an Anthony for Best Mystery in 1990. It's nice, but not super important, IMO, to read the books in order.
This series is one of the few that I have to read alone, since I tend to laugh out loud a lot - it has some of the driest British wit I have run into. I searched around a bit among the various threads here on MR, and found that a bunch of folks had read and liked
Adonis a while back - hopefully some are still around and would like to give
Sirens a try.
A while back I wrote a paean to this series in another thread - if you want to take a look, here's the link:

I'm about to get on a plane, but will come back and add links when I get a chance.
