Thanks both....I thought reef first but it doesn't fit the theme...all the perimeter words are connected with a certain word and this doesn't fit in here??
The central barred-off cell might be directional and the the perimeter gives the key name (H...) so I thought maybe the missing/damaged parts on that side?
Thanks ... i understand what you mean by the RHS but still don't see 2 (can see the one you referred to with the reef answer) missing /damaged parts of H........unless it means all his titles? And why Changing Places for the title?
