Have finished grid but still can't pair the theme words. One problem is that I seem to have 13 of them (apart from 9d & 7d). They are 5a,16a,24a,27a,29a,6d and 1a,10a,12a,17a,23a,28a and 22d. I suspect one of the latter seven is not a theme word, but they all seem to lack definition.
Can anyone help ?
