'No, that, I'm thankful to say, is a job for the Norfolk CID. Calling in the Yard happens more often in fiction than real life.'

'It's convenient that you're driving to Norfolk, whatever the reason. I wouldn't really wish to trust these proofs to the post. But I thought your aunt lived in Suffolk? And surely someone said that Miss Dalgliesh had died.'

'She did live in Suffolk until five years ago when she moved to Norfolk. And yes, my aunt has died.'

'Oh well, Suffolk or Norfolk, there's not a lot of difference. But I'm sorry she's dead.' She seemed for a moment to contemplate human mortality and to compare the two counties to the disadvantage of both, then said: 'If Miss Mair isn't at home you won't leave this at the door, will you? I know that people are extraordinarily trusting in country districts but it would be quite disastrous if these proofs were lost. If Alice isn't at home her brother, Dr Alex Mair, may be. He's the Director of the nuclear power station at Larksoken. But perhaps, on second thoughts, you'd better not hand it to him either. Men can be extremely unreliable.'

Dalgliesh was tempted to point out that one of the country's foremost physicists who was responsible for an atomic power station and, if the papers were to be believed, was strongly tipped for the new post of nuclear power supremo, could presumably be trusted with a parcel of proofs. He said: 'If she's at home, I'll hand it to Miss Mair personally. If she isn't, I'll keep it until she is.'

'I've telephoned to say that it's on its way, so she'll be

expecting you. I've printed the address very clearly. Martyr's Cottage. I expect you know how to get there.'
