Ok since tomorrow and all next week will be very busy catching up at work here goes. Malcolm has contributed a chapter to a book that was just published 2013 yes its out as 2013! Since I expressed interest as he was writing it, he has asked me to read it to see if I would detect a deliberate mistake. UNFORTUNATELY Malcolm I deleted all my Private messages to make more space too. So please kindly restate the name of the book and your chapter, for all to benefit. I said ""I will"" to reading it... no, nothing romantic.. sorry don''t get your hopes up, but it was a nice mystery though.
