Toby makes a house call on a working-class estate when Charles is down with food poisoning and Tom is unreachable because he's working for a deputizing service to supplement his salary; there's trouble with a fire-safety officer over the surgery's bricked-up door.
Toby collapses after a squash game and is admitted to hospital for further observation. To his dismay his bed is in the public ward, beside a number of NHS patients.
