This was supposed to be no more than a walk-on role with only servants and the occasional telephoto lens for company.

A few minutes performing for a bunch of journalists, and getting away with it, had given her a terrific buzz, but playing the part convincingly under the eyes of someone like Kalil al-Zaki for an entire week was a whole different ball game.

Hopefully, the letter of introduction would fill in the details, she thought as his hand fell away at the top of the steps and she was greeted by the waiting stewardess.

‘Welcome aboard the royal flight, Lady Rose. I am Atiya Bishara and I will be taking care of you today.’ Then, looking at the flowers she was clutching like a lifeline, ‘Shall I put those in water?’

Lydia, back on more or less familiar territory, began to breathe again. This was the basic lookalike stuff she’d been doing since she was fifteen years old and she managed to go through the standard ‘How d’you do?’ routine as she surrendered the flowers and the dark pink leather briefcase that exactly matched her hat. The one Rose had used to conceal the cash she’d needed for her week away and which now contained Lydia’s own essentials, including her own passport in the event that anything went wrong.

‘Your luggage has been taken to your suite, Lady Rose. I’ll take you through as soon as we’re in the air,’ Atiya said as she led her to an armchair-sized seat.

A suite?

Not that familiar, she thought, taking out her cellphone and sending a one word message to Rose to let her know that she’d got through security without any hiccups. Apart from Kalil al-Zaki, that was, and Rose couldn’t do anything about that.

That done, she turned off the phone and looked around.

From the outside, apart from the royal livery, the aircraft might look much like any other. On the inside, however, it bore no similarity to the crammed-tight budget airlines that were a necessary evil to be endured whenever she wanted a week or two in the sun.
