More later...

later update - Well! Most of Mrs FP has been uplifted from hospital. Not that I think any less of her, but there is. There was a slight debacle at reception where I wanted the offending stone which was to be attractively mounted as a pendant for Christmas, the nurses wanted it while phoning the Guiness Book of Records, however the surgeon had called dibs and it now adorns his Alpine rockery. 

Anyway, Mrs FP pointed in the right direction.

Thanks for the well wishing.
