I'm not familiar with the Times crossword, but cryptic clues don't always make perfectly logical sense, look at the definition for the word cryptic here:
I think it more likely that a word was accidentally missed off - typos do occur in newspapers, even the Times! You're right in thinking that there is no definition, and no cryptic clue would be complete without one, no matter how cryptic (unless it's a thematic puzzle with preamble, which the Times isn't). Good cryptic clues ARE logical and sound - that's the point!
Thanks again kev100 Thanks even more, Quizmonkey. With your confirmation of my view, I find that I am no longer irritated and can bin my stroppy letter to the Times. When I've solved today's puzzle life will be perfect.
