Laura entered almost at once.
"Open the laboratory," Quest ordered.

"Then come back." Without a word or a glance towards the sleeping figure, she obeyed him.

It was a matter of seconds before she returned.

Together they lifted and carried the sleeping girl out of the room, across the landing, into a larger apartment, the contents of which were wrapped in gloom and mystery.
A single electric light was burning on the top of a square mirror fixed upon an easel.

Towards this they carried the girl and laid her in an easy-chair almost opposite to it.
"The battery is just on the left," Laura whispered.
Quest nodded.
"Give me the band." She turned away for a moment and disappeared in the shadows.
