‘N Or M’ by Agatha Christie is my fourth and final read for January and is a Tommy and Tuppence Beresford mystery.
This cheeky paperback cunningly hid for 2 days with me tearing the house apart-just for a change-searching for the book (finally located under a pile of wool).
So, what’s this one about?
Husband and wife team Tommy and Tuppence are feeling past, useless yet desperate to be a part of the Second World war effort.
After being told that they are too old for active service, and supremely disatisfied with knitting balaclavas, a knock on the door provides exactly the respite that Tommy needs,
The death of undercover operative, Farquhar, has created an opening to work out who is an undercover, special operative or Fifth Columnist, feeding Allied information to the Germans whilst pretending to be one of our own. Farquhar was ‘accidentally’ run over but before dying whispered the phrase ‘N or M Song Susie’.
This is deciphered as a boarding house named ‘Sans Souci’ (without worry in French) in Leahampton on the coast-the secret service know that N is a man and M a woman so Tommy, much to Tuppence’s chagrin, leaves telling her that it is office work that he is up to, nothing remotely exciting.
Imagine his surprise when he arrives in Leahampton to recognise a familiar face…
This is a brilliant piece of detective fiction, it taps into the war time paranoia about refugees and asylum seekers which quite neatly parallels our own troubling time frame. Tommy and Tuppence put life and limb on the line trying to maintain their secret identities and uncover the cuckoo in the nest of odd people who are holidaying in Sans Souci.
If you have only ever read Poirot or Marple, this is a refreshing change to try which I would thoroughly recommend!
Next time, I will be reading ‘‘Cards On The Table’

I’ve read one of the Tommy and Tuppence books but didn’t get very excited about it, this one sounds better though.
I think they are a bit hit and miss, the best bit is they are small and quite easy to read but totally get what you mean about it not being exciting-this has proper peril in it and I think it’s because there is a realsitic backdrop of WW2 it’s maybe more relatable?
A bit of hit or miss, yes, but still I love how they age over the books she wrote, which doesn’t happen with either Marple or Poirot (okay, he does get older in the ABC Murders, but otherwise, he’s mostly the same age).
I read a different Tommy and Tuppence novel – it wasn’t great but this one sounds a lot better
