‘I don’t have all day,’ he warned.

‘No, sir.’ She took the globe and gave it a little shake to start the snowstorm. ‘Okay, this is how it goes. Spoilt princess drops her precious golden ball in the well. The frog offers her a deal. If she takes him home with her, lets him eat from her plate, sleep on her pillow, kisses him goodnight…’ She hesitated as, distracted by the sensuous curve of his lower lip, she lost the thread of the story.

‘He’s a talking frog?’

She shrugged. ‘It’s a fairy tale. If you want reality you’re in the wrong place.’

He acknowledged the point with the slightest movement of his head. Then, ‘Kisses him goodnight,’ he prompted.

‘Mmm. If she promises all that,’ she said, ‘he’ll fetch her golden ball from the bottom of the well.’

‘A gentleman frog would have done it without strings attached.’

‘A girl with any gumption would have got it herself.’

‘You would have climbed down the well, Metcalfe?’

‘I wouldn’t have kissed the damn frog!’

‘You disapprove?’

‘There’s no such thing as a free golden ball,’ she said.

‘No, indeed.’ He did something with his eyes and, without warning, beneath the dark red uniform Diana suddenly felt very warm.

‘Anyway,’ she said quickly, running a finger under her collar to let in some cool air. ‘She, um, agrees. Actually, she’d have promised him the moon-she loved that ball-and the ungentlemanly frog dives into the well, gets the ball and hands it over, at which point the princess shows her gratitude by legging it.’

‘Legging it?’

‘Has it away on her toes. Scarpers. Runs back to the palace without him.’

He laid one of those beautiful hands against his heart. ‘I’m shocked.’

She’d been quite wrong about the irony. He ‘got’ it all right. He might not be laughing on the outside, but his eyes gleamed with amusement.
