“Well,” said Dr. Martineau, extending his hand to Sir Richmond on the Salisbury station platform, “I leave you to it.”

His round face betrayed little or no vestiges of his overnight irritation.

“Ought you to leave me to it?” smiled Sir Richmond.

“I shall be interested to learn what happens.”

“But if you won’t stay to see!”

“Now Sir, please,” said the guard respectfully but firmly, and Dr. Martineau got in.

Sir Richmond walked thoughtfully down the platform towards the exit.

“What else could I do?” he asked aloud to nobody in particular.

For a little while he thought confusedly of the collapse of his expedition into the secret places of his own heart with Dr. Martineau, and then his prepossession with Miss Grammont resumed possession of his mind. Dr. Martineau was forgotten.
