Hi noviceman. If the DM cryptic is new to you remember Rome isn't built in a day.
I believe that you have to try to finish but if you are really stuck then this site is the one to consult.
You will always be offered assistance without ridicule and a breakdown will almost always be supplied when asked. This gradually gives "you a feel" as to how this particular compiler's mind works and what he is driving at. Persevere and it wont take long to get to grips with. Trust me I cut my teeth on cryptics not so long ago on this very crossword but not be quite so quick to solve,say, the Times or Telegraph yet. Vocabulary helps plus ability to see anagrams when they often appear. Good luck.Keep at it we are a friendly team here.
