It has taken ages for me to read this book because I found it uninteresting, definitely not thrilling. My heart was not in it. When it was first published in 1967, foreign travel, particularly flying, was not popular, maybe not that affordable. Reading it in 2023, I found that much of the flying in the novel is totally unnecessary, does not add any local colour or anything. Altogether I thought the novel rather formulaic; previous books and films in particular have accustomed me to this complicated telling of a story where danger lurks around the corner and there are constant quandaries, then good luck. Maybe I simply expected too much after the same author's "Firecrest" (published a few years later) that I enjoyed very much.
On the positive note I think the title is excellent and the python bracelet and the python itself were definitely photogenic, worth imagining.
