I liked this well constructed puzzle. However, I spent more time than I might have, wondering what, other than the obvious, connected the items yielding by the omissions from the across clues. I might have been spared that particular journey had the preamble said "items, each of which behaves thematically", rather than "behaving thematically", since the theme (both the thing that connects the start and finish and the drawer), is singular, not plural. Incidentally, can anyone well trained in the theme say whether they think the title of the piece should have been A3, rather than A1?
