“Cecil dear, I know you are a good teacher. I just love to hear you talking over your lessons, but you are irritable! One of my girls was crying the other day. You had given so much homework, and she didn’t understand what was to be done, and said she daren’t ask. You had been ‘so cross!’ I made a guess at what you wanted, and by good chance I was right; but if I’d been wrong, the poor thing would have been in disgrace, and honestly it wasn’t her fault! She was willing enough.”

“Oh, that imbecile Gladys Brown! I know what you mean. I’d explained it a hundred times. If she’d the brains of a cow she’d have understood. No wonder I was cross. I should have been a saint if I wasn’t, and no one can be a saint in the summer term. Did—did any one else see her cry?”

“I think not. No, I managed to comfort her; but if Miss Farnborough had happened to come in just at that moment—”

Cecil shrugged and turned the subject, but she took the hint, to the benefit of her pupils during the next few weeks.

July came in, and with it a spell of unbearable heat. In country places and by the seashore there was space and air, and clean fragrant surroundings; but over London hung a misty pall, and not a branch of the dusty trees quivered to the movement of a passing breeze. It was a thunderous, unnatural heat which sapped every scrap of vitality, and made every movement a dread.

Claire was horrified at the effect of this heat wave on Sophie Blake. In superficial fashion she had always believed that rheumatism must be better in hot weather; but, according to the specialist, such heat as this was more trying than damp or cold, and Sophie’s stiffness increased with alarming suddenness.

There came a day when by no effort of will could she get through her classes, when sheer necessity drove her to do the thing she had dreaded most of all—inform the Head that she could not go on with her work.

Miss Farnborough was seated in her private room, and listened with grave attention to what the Games mistress had to say. Her forehead puckered in surprise as she noted Sophie’s halting gait, and the while she listened, her keen brain was diving back into the past, collecting impressions. She had seen less than usual of Miss Blake during the term; once or twice she had received the impression that Miss Blake avoided her approach; Miss Blake had been looking pale. She waited until Sophie had finished speaking, her hands folded on her knee, her penetrating eye fixed on the girl’s face. Then she spoke—

“I am sorry to hear this, Miss Blake. Your work has been excellent hitherto, but rheumatism is a serious handicap. You say that this heat is responsible for the present attack? Am I to understand that it is a first attack—that you have had no threatening before?”

“I have been rheumatic all winter, more or less. Before the Easter holidays it was pretty bad. I began to feel stiff.”
