A Thriller - 'Sister' by Rosamund Lupton

Pic of sunny garden today.  Above lower - You can just see some delicate nerines flowering among all that pink shrubby salvia. It has taken the nerines five years to appear - I reckon I planted them too deep originally. I've learnt since that the bulbs should have their necks above the ground. Nerines are mostly greenhouse plants apparently and even the hardy one needs a sheltered spot outdoors. The salvia itself looked dead for months after last cold winter but as you see it isn't.  I'm cheered by these late flowering plants, aren't you?

Sister by Rosamund Lupton.  Another Richard and Judy choice, another good read, this thriller is told in the form of a letter by Beatrice to her missing sister, as in We Need to Talk About Kevin - not that there is any connection between the two apart from the format.  Here's the blurb. 'Nothing can break the bond between sisters ...When Beatrice gets a frantic call in the middle of Sunday lunch to say that her younger sister, Tess, is missing, she boards the first flight home to London. But as she learns about the circumstances surrounding her sister's disappearance, she is stunned to discover how little she actually knows of her sister's life - and unprepared for the terrifying truths she must now face. The police, Beatrice's fiance and even their mother accept they have lost Tess but Beatrice refuses to give up on her. So she embarks on a dangerous journey to discover the truth, no matter the cost.'
It's difficult to write about it without giving away the plot, but it is to do with gene therapy and cystic fybrosis, something I know a little about, but not much.  Rosamund's husband is a doctor, apparently, so she was able to research hospital procedures. I had a vague suspicion who dunnit but didn't guess the denouement. Well worth reading.  It's been a big seller, as 'literary crime'.
