I waited breathlessly. Breakfast was being cleared away, the work of the house was being done. At last, the various activities seemed to die down. I slipped out from my lair once more. Very carefully I crept down the stairs. The hall was empty. Like a flash I was across it, had unlatched the door, and was outside in the sunshine. I ran down the drive like one possessed.

Once outside, I resumed a normal walk. People stared at me curiously, and I do not wonder. My face and clothes must have been covered in dust from rolling about in the attic. At last I came to a garage. I went in.

“I have met with an accident,” I explained. “I want a car to take me to Cape Town at once. I must catch the boat to Durban.”
