Stumped by these:
22a Flourishes by writer: a gripping subject for literary collection (14). From the crossing letters seems to be Shakespeareans, if such a word exists. Can't see how it parses.

18d. The genuine article for sale? Get out of hand again (7). Assume reallot, but not sure how this means "Get out of hand again".
