My Chambers app is really getting a workout today. One more question. I now have the last group of six in the across clues, but I think my guess for the wordplay in 29 was wrong. I had s-t-e + ams, which I am confident of, but I thought "i" was removed as in spots = aims. Now I think it must be "p" removed, to make a word of the extra letters, which means spots = pams. I have run across this definition of "pam" in the Listener before, so I think I have it now. Could anyone confirm? (By the way, the word "pam" makes me uncomfortable having had a difficult girlfriend of that name a long time ago.)
