‘Steady,’ he said, helping her into the well of the gondola, which rocked, forcing her to clutch him for safety.

‘You sit here,’ he said, settling into the rear-facing seats, an arrangement that would enable him to see her face. ‘It’s better if you don’t face the front,’ he hurriedly improvised. ‘At this hour people get the setting sun in their eyes. And you might get seasick,’ he added for good measure.

‘I’ll do just as you say,’ she agreed demurely. She supposed she could be blinded by the setting sun from either direction, depending on which route he took, but she appreciated his strategy.

It suited her, too, to be able to lean back and stretch out her long, silk-clad legs before his gaze. True, she was supposed to be tempting him with the prospect of money, but there was no harm in using the weapons nature had bestowed.

He cast off, and for a while they went gently through narrow canals, where buildings rose sheer out of the water. They glided under a bridge and as it slid away she saw that it seemed to emerge direct from one building, over the water and straight into another. Dulcie watched in wonder, beginning to understand how this city was truly different from all others.

He was a clever man, she thought. He knew better than to spoil it by talking. Only the soft splash of his oar broke the silence, and gradually a languor came over her. Already Venice was casting its spell, bidding her forget everything but itself, and give herself up to floating through beauty.

‘It’s another world,’ she murmured. ‘Like something that fell to earth from a different planet.’

An arrested look came into his eyes. ‘Yes,’ he said. ‘That’s exactly it.’

They seemed to drift for ages, one beauty crowding on the last, too many impressions for her to sort them out. Vaguely she remembered that this wasn’t why she was here. Her job was to work on the man standing there, guiding twenty-two feet of heavy, curved wood as though it was the easiest thing in the world.
