‘He was your father’s cat …’ I ruminate, trying to work out the wider implications of this unwelcome detail, somewhat on the hoof, I’ll admit. ‘And I suppose that horrendously fat dog I see you dragging up and down the beach every morning and evening is your father’s dog?’

‘Strictly speaking, he was my late mother’s cat,’ she explains (ignoring the dog comment). ‘He’s called Rolfie. He’s forty-one years of age.’

‘The average life expectancy of a cat is fifteen,’ I say, incredulous.

‘Yes. I know.’ She nods, solemnly. ‘Rolfie is an incredibly old cat.’

‘So Rolfie has lived almost three times longer than the average cat?’ I persist, then promptly calculate: ‘The equivalent age – in a person – would be two hundred and ten.’

‘Yes,’ she confirms, patently unshaken by the comparison.

I just can’t let this one go. ‘Doesn’t that strike you as a little … uh … improbable?’ I wonder.

‘Yes’ – she nods again – ‘highly improbable. It’s perfectly amazing. A miracle of nature. And then your wife drove straight into him. Drunk. In broad daylight. At high speed.’

‘Oh. Well, I apologize for that,’ I mutter.

‘My father was rather traumatized,’ she idly adds, gazing dreamily at the clouds scudding across the sky above my head.

‘In all my born days,’ I muse, ‘I’ve never heard of a cat living to forty-one years of age. He must be the oldest cat in the world. The oldest cat in the known universe.’

‘You have a ladybird on your fringe,’ she murmurs, squinting slightly. ‘In fact you have two. Yes. Two. They appear to be … to be copulating.’

‘You have very red hands,’ I respond, swiping at my fringe.

‘I’m allergic to disinfectant.’

‘Then why don’t you wear rubber gloves?’ I demand.

‘And latex,’ she adds.

In truth I’m not entirely certain if there are two ladybirds on my fringe. This worries me. I’ve had no previous intimations that Miss Hahn might turn out to be an unreliable witness. Quite the opposite. A little mouse. I was told. A lamb. Wouldn’t say boo to a goose. I was told. Damn. Damn. A propensity towards lying could prove catastrophic to my plans.

‘Anything else?’ I wonder.

‘Sorry?’

Her eyes are back with the clouds again. She seems to find great solace in the clouds, much as I do myself.

‘Allergies?’

‘Uh, nickel,’ she confirms, ‘and arrogance.’ She smiles. ‘You?’

‘Bullshitters.’

‘Oh, me too.’ She nods, most emphatically.

I can see now that this isn’t going to be all plain sailing. A short silence follows, punctuated by the cries of several gulls and the shrill whistle of a farmer in a nearby field, directing his sheepdog from the comfort of his tractor cab.

‘I’ll need to pop around to the cottage and have a look at that table,’ she eventually murmurs; ‘perhaps you might provide me with a convenient time to come over when you know for certain that you’ll be out?’

I’m still fiddling with my fringe.
