Ho Ho Ho! Happy Christmas everybody!
Posting this now not because I need help this time (so Trux, no sweating it, eh?) but because I am also concerned about where 4118 will be located. There is a paper on Sunday, isn't there? Boxing Day ought to have it - but maybe 27th as suggested? I can't imagine them missing out a Listener for a week - this has never happened before in the years I've been collecting them. Also, I buy the paper rather than subscribing to Times Online or whatever it is, so don't want to miss it.
With regards to 4117, don't know if I'm the only one who did this, but my solution involved no detachment whatsoever; not even little doors. (That clue is already out).
i just overwrote numbers with the associated letters from grid B in happy jolly red ink on grid A (as well as those that were already there) and posted it, along with a real crimble card in case hitherto unincluded parties (statisticians, for example) were feeling left out. Needless to say, they ought to have it by now.
Merry Xmas everyone, and a happy new year!
