I did as I was told. But if in my heart I had vaguely hoped that I should then and there be confronted with the solution of the mystery which surrounded the Somersetshire outrage, I was doomed to disappointment.

Each of the marked paragraphs in the “Personal” columns bore the initials H. S. H., and their purport was invariably an assignation at one of the small railway stations on the line between Bristol and Weston.

I suppose that my bewilderment must have been supremely comical, for my dear lady’s rippling laugh went echoing through the bare, dull hotel sitting-room.

“You don’t see it, Mary?” she asked gaily.

“I confess I don’t,” I replied. “It completely baffles me.”

“And yet,” she said more gravely, “those few silly paragraphs have given me the clue to the mysterious assault on Jane Turner, which has been puzzling our fellows at the Yard for over three weeks.”

“But how? I don’t understand.”

“You will, Mary, directly we get back to town. During my morning walk I have learnt all that I want to know, and now these paragraphs have set my mind at rest.”

The next day we were back in town.
