These are cryptic clues and all the answers either begin or end with A
The clues are as iver first descibed them; that is
18. A jolly, old fellow in the last war (10)....first two letters refer to a jolly then a word for old then a word for fellow
22 Write off in a recess (8)...Starts with A, then a type of lock
31. Legal notes made in error about Moriartys assiostant (9)....an anagram of "made" around the name of Moriartys assistant.
It is quite a difficult quiz of 100 questions, I have just about finished it, although uncertain of some of my answers
