This is a cryptic crossword puzzle with two sets of clues sharing the same answer grid. The answers to each set of clues form a chain, the last letter of each answer being the first letter of the next. One chain runs through the grid horizontally, the other vertically.
This would prove a good puzzle for cryptic novices, as the two sets of clues are actually an aid to solving. The answers to one set of clues will place the letters of the answers to the other set of clues. Just be careful when skipping an answer, to leave the right number of empty cells.
Devising such a puzzle in which not only is every cell of the grid occupied by a letter, but in which each letter counts at least twice, is an extremely tricky task for the compiler.
