My late grandmother apparently claimed that crime writer Agatha Christie stayed with her family during the period the writer was missing in the 1920s.

Grandma was not one to make things up and I wondered if anyone else had heard this story - we think she would have been living in Argyle St South in Birkenhead at the time.

Nope would love someone who has tho

Sounds fab

Wikipaedia suggests that Ms Christie's disappearance related to her Husband's infidelity, which later on led to them divorcing (whether or not she had a breakdown or depression, which apparently her Mother suffered from, according to Wikipaedia, and scarpered off to Yorkshire). This produced a scare, with some even suggesting that her husband had done away with her!

There is a book available 2nd-hand on Amazon relating to this, link as follows:-

Agatha Christie and the Eleven Missing Days

I don't know if this would assist you or not.

Good luck!
