Rusty. I thank you for the clarification link. I have always enjoyed challenging crosswords and puzzles but this particular version of tbe Rainbow Quiz seems to contain more than the usual amount of obscurities, which it is not possible to solve without either access to the blessed Chambers or very specialist knowledge. I am one of those who believe that to attract the largest number of entries, a charity quiz should be, yes, challenging, but not requiring either of the above to solve. There are plenty of ways to challenge without having to delve into arcane and archaic words and expressions. I am grateful to those who have helped me to complete the puzzle, without whom I would have been unable to do so.
