It was midnight at Coblenz, and the travellers had retired to rest in their respective apartments, overlooking the river. Finding that there was a moon shining, Paula leant out of her window. The tall rock of Ehrenbreitstein on the opposite shore was flooded with light, and a belated steamer was drawing up to the landing-stage, where it presently deposited its passengers.
'We should have come by the last boat, so as to have been touched into romance by the rays of this moon, like those happy people,' said a voice.
She looked towards the spot whence the voice proceeded, which was a window quite near at hand. De Stancy was smoking outside it, and she became aware that the words were addressed to her.
'You left me very abruptly,' he continued.
Paula's instinct of caution impelled her to speak.
'The windows are all open,' she murmured. 'Please be careful.'
'There are no English in this hotel except ourselves. I thank you for what you said to-day.'
'Please be careful,' she repeated.
'My dear Miss P----'
'Don't mention names, and don't continue the subject!'
'Life and death perhaps depend upon my renewing it soon!'
She shut the window decisively, possibly wondering if De Stancy had drunk a glass or two of Steinberg more than was good for him, and saw no more of moonlit Ehrenbreitstein that night, and heard no more of De Stancy. But it was some time before he closed his window, and previous to doing so saw a dark form at an adjoining one on the other side.
