Evening all - finished the grid (unusually!) yesterday lunch time, and I have the thematic, anagrammed words, and the book, and who thanked, for what, before going etc. etc.. Although I have some ideas about what to remove, and potentially what might replace it, scanning at the grid for hours today hasn't helped. Any hints greatly appreciated!
I'm being thick Masie So long a the...for......the f... and the large brained aquatic mamals departed the 3rd planet from our sun.... so a word for thank you replacing a 5 letter word for a very large body of water? Or a worf for a large numer of f...? LOL
