'Very well,' he decided at last, 'let me help and I will be content with a copy of the formula.'
She smiled.
'That is rather sensible of you,' she said. 'To tell you the truth, I require your help. For reasons which I need not explain, we do not wish this matter to be dealt with in any way officially. I am in perfect accord with the English Secret Service, but we do not wish to have their men seen about the Milan Mansions. To-night, Jules re-enters into possession of his rooms. I offer you an adventure. It is what you wish?'
'But I thought Jules was interned?'
'He was and is,' she told him, 'but the greater powers are working. This afternoon he will be permitted to escape—he thinks through the agency of friends. He will come to London in a motor-car, he will come at once to his rooms, and, although every inch of them has been searched, I am perfectly convinced that somewhere in them or between them and the Milan, he will lay his hands upon the formula. You care about this adventure?'
His eyes flashed.
'Care about it!' he repeated enthusiastically.
She smiled and rose to her feet.
'Leave me now,' she begged. 'I want to speak to one of those men for a minute. You can dine with me in the Grill-room at the Milan at seven o'clock, in morning clothes. Till then, au revoir!'
