‘Maybe you should take a trip to Casualty?’ she suggested. ‘Just to be on the safe side.’

‘I’ll be fine.’ Then, ‘So where is she? Adele.’

He sounded as if he might have a word or two to say to his sister about inviting someone he didn’t know to move into his house.

‘She’s bug-hunting. In Sarawak. Or was it Senegal? Or it could have been Sumatra…’ She shrugged. ‘Geography is not my strong point.’

‘Bug-hunting?’

Probably not quite precise enough for a philologist, Ellie thought, and, with a little shiver that she couldn’t quite contain, said, ‘She’s hunting for bugs.’ Which was quite enough discussion about that subject. ‘She’s away for six months.’ She made a gesture that took in their surroundings. ‘She wanted me to make the place look lived in. As a security measure,’ she added. ‘Turning lights on. Keeping the lawn cut. That sort of thing.’

‘And in return you get free accommodation?’

‘That’s a good deal. Most house-sitters expect not only to be paid, but provided with living expenses, too,’ she assured him, while trying out her legs to make sure they were in full working order, since she was going to need them later. The one with the twinge suggested that the evening was not going to be much fun. ‘And they don’t throw in cleaning for free.’

‘No, I’m sure they don’t.’ Then, having watched her gyrations and clearly come to the conclusion that she was a lunatic, ‘Will you live to dust another shelf, do you think?’

‘I appear to be in one piece,’ she told him, then gave another little shiver-and this time not because she was thinking of Adele Faulkner and her beloved bugs, or even because she was hoping to gain his sympathy, but at the realisation of how lightly she’d got off. How lightly they’d both got off. ‘What on earth did you think you were doing, creeping up on me like that?’ she demanded.

‘Creeping up on you? Madam, you were so wrapped up in the book you were reading I swear a herd of elephants could have stampeded unnoticed beneath you.’
