As promised, a cast list as complete as I can manage:
N.b. The dogs and horses quota do matter. The couples follow each other and copy, one big dog and one smaller one for example. All frequently walked together. Also boys who plays rugby... The number of children they have is also important although others could be staying over, or away at university... If I have made any mistakes I apologise and await correction. (By comment, not spanking).
Max Dunster, online football game player extraordinaire, is married to Jenno. They have two children Jamie, 11, school rugby player, and Rosie, 14. This is a second marriage for generous hearted Max. He has a son from his first marriage that no one has met. He owns and is MD of a busy local firm specialising in luxury gifts. Jenno/Jen/Jenny is a CAB volunteer. They have horses and two dogs called Beauty and Ella.
Tom Rutherford is married to Dr. Emily, a conscientious local GP. He is a security advisor and an amateur historian, presently working on a pamphlet about the four houses the `Eight' occupy in Middlebury. They have three children, Phoebe, Felix and Henry. They have dogs, Buster and Hector. They have a tennis court.
Simon Lonsdale is married to Tasha. His is something shaky in PR (`Director of Public Relations for a leading bank') and she runs a small, now run down, catering company. They have three children at home, Josh, Henry and Polly. Their dogs Clooney are and Sprout.
Jonny Crossan QC is married to laviscious Libby who even tweets her love life. He is at the top of his game, but suffering from some inner turmoil. He's from the upper class; his father sold him the house. Libby is a JP and Chair of the Parish Council. They have four children, Tilly, Plum, Lucas and Hugo. They have a nanny called Abby, dogs, Colonel and Scruff, and a horse, Glory. The coffee guy is booked to come on Saturday morning, while they are away. Is this a usual thing?
On the sidelines, like a Greek chorus, are Nicky Mortimer, a banker and Monifa his wife. They have two children, Nina is their teenage daughter. Their dogs are called Monty and Biscuit.
Underemployed graduate Jason from CappuccinGo (sounds like something to do with little monkeys but of course it's specialist coffee) is the unfortunate discoverer of the mass slaying that prologues the book. He draws up to a `dream home', `the week before the clocks change to British Summer Time' to a frosty scene of carnage beginning with his discovery of two pet dogs, shot dead, close up, through their heads. Horrid stuff.
