The seventh book in the Travis McGee series, Darker Than Amber is another solid, straight-forward mystery from John D. MacDonald. According to the description, “Travis McGee never shies away from damsels in distress. But this Eurasian beauty was different. When Travis and Meyer rescued her from the water, she had a block of cement wired to her feet, and she wasn’t so much grateful as ready to snare them in a murder racket to end all murders.” Published in 1966, this novel is still an enjoyable read, especially the Audible Original version.
