I love Cold War spy stories. I've read a lot of them, and this is one of the good ones. Having said that, I'm afraid it would be hard for me to recommend The Key to Rebecca to anyone I actually KNOW because of the insanely graphic sex scenes Follett felt the need to include. Are they well written? Well, yes they are--if you're looking for porn in novel form. Were they necessary in furthering the storyline or fleshing out the characters (no pun intended)? Certainly not to their graphic degree. I'm not a prude (Outlander by Diana Gabaldon is unapologetically my favorite novel series), but this was just ridiculous.
