Maybe him, although they are quite far from HMN. The post seemed to indicate they had a chateau near SSB. "I am a chateau owner new CDLL". I am assuming of course that 'new' is a mistake and it should read as 'near'.Would this not be the owners of the chateau who recently had to sell? All the clues are there. I think it could be the chap, the partner of Miss Anna. ??
Saying that further on it is written .. a "dear friend", who is an opera singer, "lives a few miles from SJ".
There is also someone else who is connected to SSB who is a writer. The man who wrote the novel about a murder? set in his chateau and then he was setting his next book at la la lande. I think SSB and mini-apron visited him.
I'm not suggesting he is Limogesfairy (you never know) but I do wonder if he has ever read here or even posted.
