Hi Hugh,
The crossword is EV 1597 and, while it was very enjoyable, its infamy is more concerned with my complete and utter meltdown - as illustrated (see what I did there 😄) in the corresponding thread. Thankfully, Malone and Drxx were the much needed voices of reason throughout, and all ended well. In fact, it got to the point where we could all have a good laugh about it. I believe some quotes from This is Spinal Tap even entered the conversation!
Obviously though, should you want to do the puzzle, it might be best to avoid the thread in question as it contains several spoilers or, should I say, several [I]more[/I] spoilers.
