This was a bit odd. There are chapters from the perspectives of various characters, but perhaps the most prominent is that of Colette the tech consultant, who charges large amounts of money to come and sort out things like forgotten passwords, shattered screens and parental controls, all things which I personally have no difficulty managing myself (and my children would tell you I am no tech wizard, and I'm older than most of the people portrayed here as being dependent on Colette). Having spent a fortune on her services they are always asking if they can get the screen fixed rather than getting a whole new device, which seemed like a bizarre set of attitudes to spending.

Lots of Colette's clients are clustered in a particular London square and they all have secrets and most have reasons to dislike new tenant Leila, but who killed her...? There were a lot of 'issues' going on here, some of which were not particularly developed - what was the point of all that stuff about Colette's mother? and there was at least one character who needed therapy asap. There was a fair amount of clever misdirection, but I was underwhelmed overall and never felt particularly invested. ( )
