I'm pretty sure I've never read an Agatha Christie which hasn't been a solid 5 star. This was a reread, but it's been long enough since I last read it to have forgotten who did it. The copy I read is from my own collection of about 50 Agatha Christie books I have, all picked up from garage sales and second hand book shops over the years. This is a 1966 edition, with the original offensive name and rhyme, both pretty jarring to read. There was also a you're/your mispelling which amused me because I associate it with the the noughties and the rise of Internet use.
