Times Cryptic Jumbo 1745 – 9 August 2025. Unfinished business

Hi all. This was all going wonderfully smoothly … until I slowed to a crawl. I then hit a brick wall which seemed so unyielding I resorted to word searches with a handful to go. Thanks to the setter for the brain exercise. Although I confess I got a teeny bit grumpy at the end, I enjoyed it until then!
