Mary, with a wisdom greatly beyond her years, realised very quickly that this was some sort of horrible disease, with which she must wrestle alone.

Above all, she must never allow Jeremy to know anything about it.

He was, of course, sublimely unaware of the matter; he knew that Mary was silly sometimes, but he attributed that to her sex; he went on his way, happily indifferent whether anyone cared for him or no...
Mary suffered agonies when, as sometimes happened, Jeremy sat with his arm round Helen's neck and his cheek up against hers.

She suffered when, in a mood of tempestuous affection to the whole world, he kissed Miss Jones.

She even suffered when he sat at his mother's feet whilst she read "The Dove in the Eagle's Nest," or "Engel the Fearless." Most of all, however, she suffered over Hamlet.
