LADY. But....
STRANGER. Supposing he could hear what we say! I don't trust him.
DOCTOR. What shall we do to amuse our guest?
LADY. He doesn't care much for amusement. His life's not been happy.
(The DOCTOR blows a whistle. The MADMAN comes into the garden. He wears a laurel wreath and his clothes are curious.)
DOCTOR. Come here, Caesar.
STRANGER (displeased). What? Is he called Caesar?
DOCTOR. No. It's a nickname I gave him, to remind me of a boy I was at school with.
STRANGER (disturbed). Oh?
DOCTOR. He was involved in a strange incident, and I got all the blame.
