"Good-bye." Mr.Tredgold said "Good-bye," and with a furtive glance at the window above departed.

Miss Drewitt, opening the door, looked round an empty room.

Then the kitchen door opened and the face of Mr.Tasker, full of concern, appeared.
"Did you get wet, miss ?" he inquired.
Miss Drewitt ignored the question.

"Where is Captain Bowers ?" she asked, in a clear, penetrating voice.
The face of Mr.Tasker fell.

"He's gone to bed with a headache, miss," he replied.
"Headache ?" repeated the astonished Miss Drewitt.
