Prize crossword No 26,974

Special instructions: Each clue leads to two solutions, one or both of which contain a trio (or in two cases a quartet) of successive letters of the alphabet, appearing either forwards or backwards. In one case, these letters involve the beginning and end of the alphabet; in another, the letters to be included are a mix of three successive letters. These groups of three or four letters are to be included in the full version of the solution to be entered in the grid, but are omitted from the wordplay in the clues.
