Imagine my horror to discover that I'd been betrayed. I knew it was one among five of my most trusted inner circle, so I sent them this message:

Dear Anna, Bess, Chrissy, Diana, and Eva,

I know one of you has done the dirty on me behind my back. If you are good enough to admit it, we can put it behind us and move on. If any of the rest of you know who it was, remember it is no disloyalty to rat out a rat - if you know something, please say (privately).

Freya x

I received the following replies:


It wasn't me, but that's all I know.



Hi Freya,

I saw Anna and Chrissy whispering about something the other day, but I suppose that could have been about anything. So sorry this has happened to you.

Bess xoxoxoxox

I think it might have been Diana, but please don't tell her I said anything.

Hugs and kisses,


Oh, no! I can't believe anyone would do that. Mind you, you know I've never fully trusted Eva - I bet it was her.

Hope you get over this soon.

Diana xx

Dear Freya,

That's awful - but I did warn you Bess was not to be trusted.

Lots of love,

Eva xxx

From these messages, can you tell me who I should unfriend, and how you can tell they are the one who has stabbed me in the back?

  • $\begingroup$ @Amoz You are essentially asking, "Is it so-and-so, because of such-and-such?" That should be an answer not a comment. $\endgroup$ Commented May 11, 2021 at 12:01

I think the answer might be



She ended her message xx - indicating a double cross

Possibly wrong but I'll put this out there as a guess as it hasn't been specifically denied.
If we are looking for someone who has 'done the dirty', it is interesting that

Eva replied xxx (associated with dirty) whereas the others replied with hugs or kisses. Perhaps it was an unconscious slip on her part, indicating guilt.
Next steps could be to have a private talk with Eva and discuss your concerns, and try to reconcile the relationship if indeed it was her. If she is unwilling, unfriending could be in order. Otherwise reconciliation and forgiveness on both sides is to be hoped for. Or perhaps it wasn't her at all, and more time studying these replies is in order.

  • $\begingroup$ Close but no cigar, I'm afraid. $\endgroup$ Commented May 11, 2021 at 16:50

I think,


If only one of this inner trusted circle is not to be trusted, and if Eva is trustworthy, then both Bess and Diana are not. On the other hand, if Eva isn't trustworthy, then Diana's comments are correct, and Eva's comments about Bess aren't trustworthy.

  • $\begingroup$ Nice, logical reasoning, but no. Don't forget to check a puzzle's tags. $\endgroup$ Commented May 12, 2021 at 6:48

I think it was

Anna, because all the other messages (including yours) ended with kisses (either word or just “x”), except hers - she only sent you hugs.

  • $\begingroup$ Another one that is in the right area, but not right, I'm afraid. $\endgroup$ Commented May 12, 2021 at 6:49
