Stuck on a couple, first time trying to do this xword, answers appear mostly cryptic.
11a) first take some cookery books. (5)T?M?S (think it's tomes)
17d) live on a ship, i.e. the Elizabeth. (6) ?E?K?E (? deckie)
21a) undefined organisation? (6,7)S???E?N?T?O?? (? NETWORK)
ANY INPUT GREATLY APPRECIATED, SOME CRYPTIC I CAN RECONCILE BUT STUMPED ON THESE. ;)
