She caught herself in time and broke off, heart thumping, horrified by what she’d so nearly revealed.

There was a pulsing silence.

‘What did you discover, Katy?’ He was suddenly incredibly still and his dark eyes were watchful.

‘Nothing.’ Her voice was a strangled croak and he muttered something in Spanish and moved towards her.

But whatever he’d intended to say, the opportunity was lost as the mother and toddler returned with their X-rays.

Filled with relief at the reprieve, Katy checked them carefully, aware that he was standing close behind her, feeling his warm breath on the back of her neck.

‘She’s fractured her radius.’ Trying to ignore the tense atmosphere, Katy squinted at the X-ray, visually tracing the cortex of each bone as she’d been taught, looking for irregularities. ‘There’s a slight displacement,’ she murmured, ‘but that shouldn’t matter in a child this young so I’ll just give her painkillers and immobilise it in a cast.’

Jago’s eyes flickered to the X-rays. ‘Have you checked for a second fracture?’

Katy frowned. Was he still trying to catch her out?

‘Yes.’

‘So what makes you so smart, Dr Westerling,’ he muttered under his breath, and she gave a slow smile, ridiculously pleased by the veiled praise.

‘I worked in paediatrics,’ she reminded him lightly, tugging the X-ray out of the light-box and returning it to the folder.

From a professional point of view, working with him was definitely getting easier. He no longer made her feel as though she should be back in medical school.

Unfortunately their personal relationship was much more complicated.

Katy discussed the management of the fracture with the mother, all the time aware that Jago was standing there, biding his time.

Suddenly she felt hideously nervous and she was desperately searching for an excuse to escape from him when Charlotte hurried down with the news that Ambulance Control had rung to say that they were bringing in a nasty head injury.

With a look of savage frustration on his lean, handsome face, Jago departed, leaving her in no doubt whatsoever that the subject wasn’t closed.

CHAPTER SIX

JAGO rang the bell of the flat with impatient fingers and proceeded to pace up and down like a caged tiger.

Ever since their totally unsatisfactory, interrupted conversation, he’d been filled with a rising tension and foreboding.

What had Katy been about to say when she’d stopped in mid-sentence?

Obviously something that she would rather have kept a secret, he reflected grimly, remembering the sudden pallor of her cheeks.

The door suddenly opened and Libby stood there, her blonde hair tumbling over her shoulders, a defiant gleam appearing in her eyes as she recognised him.

‘Yes?’ Her tone was decidedly unfriendly and he tensed. He wasn’t accustomed to receiving such a complete lack of response from a woman.

Obviously he had some serious fence-mending to do with the sister as well as Katy.

‘I need to talk to your sister.’

‘She’s got a date with Freddie tonight,’ Libby announced smoothly. ‘He’s the man she’s marrying in two months’ time.’
