The Evil Shepherd by E. Phillips Oppenheim

It was after leaving Miss Daisy Hyslop's flat that the event to which Francis Ledsam had been looking forward more than anything else in the world, happened. It came about entirely by chance. There were no taxis in the Strand. Francis himself had finished work for the day, and feeling disinclined for his usual rubber of bridge, he strolled homewards along the Mall. At the corner of Green Park, he came face to face with the woman who for the last few months had scarcely been out of his thoughts. Even in that first moment he realised to his pain that she would have avoided him if she could. They met, however, where the path narrowed, and he left her no chance to avoid him. That curious impulse of conventionality which opens a conversation always with cut and dried banalities, saved them perhaps from a certain amount of embarrassment. Without any conscious suggestion, they found themselves walking side by side.
