'One must remember,' he observed reflectively, 'that it is not only for our own safety—it is for the preservation of a great cause.'

Lavendale took a cigarette from a box in the centre of the table, and lit it.

'I don't know what this penalty is that you propose to inflict upon us,' he remarked, 'but I should just like to remind you that you are living in a very highly civilized country, where people do not disappear.'

'At Hookam,' Mr. Silburn said calmly, 'people have disappeared for the last nine hundred years. Below there, the secret cloisters reach almost to the sea. The cleverest and most astute criminologists who ever breathed might track you to these doors, Lavendale, and search until their hair was grey before they discovered a single trace of you. My servants are mine, body and soul. For my wife's sake, Lavendale——'

'Look here,' Lavendale interrupted, 'I am not sure whether you are in earnest or not, but whatever you might be thinking about for me, you couldn't be such brutes——'

He stopped short. There was a sudden light in his face. From outside the door they could clearly hear the sound of an angry voice. A little ripple of terrified excitement flashed around the table. Mr. Silburn's teeth came together with a little click. There was a curious tremor of emotion in his tone.

'Lock the door,' he ordered Barracombe.

It was too late. In a long travelling ulster, with his cap still in his hand, Major Elwell stood already upon the threshold. Behind him, still protesting, was Lydia Silburn.

'Elwell!' Lavendale shouted. 'Thank God!'

Major Elwell gazed around at them all through his eye-glass and looked back at the woman by his side. He seemed bewildered.
