Aunt Gladys had died at eighty-six in a nursing home, leaving the house furnished. Though much of it was old and worn, they had kept the better pieces to kit out some of the bedrooms. The downstairs rooms, apart from the kitchen and one turned into a communal lounge, were given over to the needs of their practice. As well as the office, there was a large laboratory and a workroom each for Angela and himself, together with a toilet at the end of the corridor that led back from the central hall. A preparation room and wash-up for apparatus occupied the former scullery and what had been a huge pantry was now to be a storeroom.

As they finished their drinks, there was a throaty roar from outside as a motorcycle climbed the steep drive from the main road below and swung around the back of the house to the yard behind. Here there was a coach-house with space for two cars underneath a large loft that Angela had her eye on for an extension to the laboratory. With a final noisy revving, the engine of the Royal Enfield died and moments later the rider and his passenger marched into the office.

‘Jimmy saw me at the bus stop and gave me a lift,’ announced their sole professional employee. Sian Lloyd was a lively, ebullient blonde of twenty-four, small and shapely, with a snub nose and blue eyes. Not a girl to be pushed around, she gazed out at the world defiantly, speaking her mind on anything that concerned her – and some things that did not. Sian came from a working-class family, her father a welder in a local engineering works, a shop steward and fervent socialist, some of which had rubbed off on his daughter. She was fully qualified, having passed all the examinations giving her Fellowship of the Institute of Medical Laboratory Technology, and she had already started on an external degree in biochemistry.

‘Here’s the licence – and the stamps.’ She placed an envelope on the table in front of Angela. ‘Jimmy’s left the groceries in the kitchen.’
