When Michael is invited by his friend and fellow student to attend his sister's 18th birthday party, he quickly falls in love with the eccentric and bohemian Hanbury family of Egypt Hill, a wonderful old house nad large sheepfarm in Devon.

We're never told much about Michael's background, but can only surmise that it must have been pretty dull for him to have been so easily seduced by this apparently chaotic and Bohemian extended family.

We then skip a decade or two. Michael is an established lawyer and has married into a family which shares many similarities with the Hanbury's: the Alexanders are wealthy, aristocratic and unconventional. But his relationship with his wife Rebecca is uneasy: she seems to be going through a crisis after the birth of their son, Hamish. When the balcony of their Georgian townhouse in Bath falls and almost kills him, it is clearly symbolic of the state of their marriage.

Then Adam gets in touch. His father is in hospital having a prostate operation. It's the lambing season and Adam could use another pair of hands. Michael decides to use the opportunity to take a break from his marriage, and carts the non-communicative Hamish along with him.

Egypt is little changed, although ugly modern development encroaches on the hill and has swallowed up much of the town. The Hanburys don't improve with requantance: Michael witnesses the family bickerings and machinations, and in a climactic scene in the farm's kitchen, the disclosure of ugly secrets buried for decades.

Cusk's great strength is in careful social observation and fine detailing, and In the Fold is an extremely interesting comedy of manners. Michael is a strangely inert central character which makes him the perfect observer of the drama unfolding at Egypt ... and also in his own home. The characters are very well drawn and most quite stunning in their awfulness.

There's a lot of dialogue - in fact in many of the scenes nothing happens but talk, so that it felt, at times like reading a playscript. But the conversations are so totally revealing of the characters, brilliantly observed and often very funny.

But maybe I wasn't concentrating hard enough because I kept getting confused about who was who in the Hanbury clan (there's a large cast of minor characters) and had to flip back the pages. Annoying! ( )
