Part-way through The Spy Coast by Tess Gerritsen I thought, ‘She’s done such a great job with these characters this will have to become a series.’ And sure enough, after I’d finished reading I went to add it to Goodreads and noticed it’s called The Martini Club #1.

It’s very reminiscent of Richard Osman’s Thursday Murder Club series – though given our lead cast are all ex-CIA agents – they’re like the residents of the Coopers Chase Luxury Retirement Village, but on speed.
