On Saturday nights they are allowed, within reason,
their freedom. This means alcohol. The Combe Abbey rules
about alcohol are perfectly clear: never before the sixth form
and, if every term a shcoolboy’s stomach or two has to be pumped,
there is no need to discuss it. On returning from dinner out
(never just drinking) on a Saturday night, Combe pupils
must report to their housemaster. Why the housemasters
never notice that everyone is completely drunk is a mystery.
It has happened to Marina twice already; she remembers
nothing at all of the first time, and the second she insisted
on walking in a straight line and broke a chair leg. There
are always awful stories: paralytic staggerings into the arms
of the headmaster’s wife, vomit in the Chapel. Today
is the birthday of Selina Knocker, the sweet but stupid child
of the head of the navy who is, physically at least, in Marina’s
classes. This must be why Marina is invited.
She is wearing contact lenses. Dust and drizzle and her
own fringe keep blowing into her eyes as she walks along the
dark East Combe Road, next to Selina’s cousin Gypsy. No
one brings coats, let alone their great-aunt’s umbrella from
Fenwick’s, so Marina’s teeth are chattering, which she is
trying to disguise with conversation. Because this part of
Dorset is so very flat and ringed by hillsides, she often has
a feeling of being cut off from the rest of England, as if
they are walking at the bottom of a meteor hole.
Gypsy, Jippo, is unfriendly but very beautiful, with long
brown legs and big blinky blue eyes. Apparently she has just
been skiing and seduced an instructor. Marina is struggling
to find common ground.
‘Where are we going?’ she asks, after an awkward silence
through which Jippo sails, serene. ‘I mean, I know the name,
but I haven’t . . . is it a, a smart restaurant? I mean—’
‘Just Capote’s.’
‘Oh. Thanks.’
