'I got hold of the dinner cards,' he announced in triumph. 'His name is Lieutenant-Colonel Leychelles.'

The little company of soldiers at that moment began to descend the steps. Suzanne rose to her feet and, standing under the shadow of the trees, she leaned forward. The man whom she had been watching with so much interest, was distinctly swinging his left arm. She gripped Lavendale by the elbow.

'Come with me,' she insisted. 'Come with me at once. Take me up to town.'

He obeyed promptly. They passed through the house and Lavendale ordered up his car.

'Where to?' he asked, as he took his place at the driving wheel.

'I must find General Matravers,' she declared. 'Drive up towards London. I must think as we go.'

They glided down the drive, over Hammersmith Bridge and up to the Park.

'Don't you belong to a club somewhere?' she asked. 'We must get a Who's Who.'

'Why, of course,' he answered. 'We can manage that easily enough.'

He pulled up presently outside the door of the Bath Club in Dover Street.
