At last, he was out of the Court.

At last, he was back at Gresham Terrace.

As his taxi turned in from the end nearest Piccadilly, he saw the small crowd gathered outside Number 22, where he lived. Several were young women, several were middle-aged; there were two or three elderly men as well as a young exquisite in a sapphire-coloured velvet jacket, green, cravat-type tie, and stove-pie trousers.

Yet for the moment he was blinded—and suddenly he was in the middle of a surging furious mob. Above the shouts of anger came a woman’s sudden cry of fear, drowned by the policeman’s bellow:
