Hello - I am Miriam Horwood, now aged 63 and three quarters! I lived at 138 Crystal Palace Road from 1950-1961 in which time my dad, a fanatical DIYer did a huge amount of work to the house. As someone has said, it was all about covering up all the lovely original features including the door and banisters. He also painted the banisters bright red! In addition to the two letters found I think I also left one in the boarded over fire place, I believe, in the basement back room but I cannot be sure. It is really interesting to hear that my letters were found as I have referred to them every now and again and wondered if or who might have discovered them. Alas, I am pretty sure no gold sovereigns were hidden! We moved away to Kent, to a bungalow, and both my parents are now dead but they would have been really interested to know that my letters were found and that Dad's panelling had lasted all those years. It was just a fluke that I googled my name and found this website. I note that it was in 2009 that all this interest was going on so hope I am not too late to get in touch.
