While the invalid in the pleasant lodgings overlooking Hyde Park grew day by day weaker, there was a change as marked in the bright young creature whose loving spirit had first brought the influence of affection to bear upon Diana Paget's character. Charlotte Halliday was ill--very ill. It was with everyday increasing anxiety that Diana watched the slow change--slow in its progress, but awfully rapid to look back upon. The pain, the regret, with which she noted her father's decay were little indeed compared with the sharp agony which rent her heart as she perceived the alteration in this dear friend, the blighting of this fair young flower. That the withered leaves of autumn should fall is sad, but natural, and we submit to the gloomy inevitable fact of decay and death. But to see our rose of roses, the pride and glory of the garden, fade and perish in its midsummer prime, is a calamity inexplicable and mysterious. Diana watched her father's decline with a sense of natural sorrow and pity; but there was neither surprise nor horror in the thought that for him the end of all things was drawing nigh. How different was it with Charlotte--with that happy soul for whom life and love wore their brightest smile, before whose light joyous footsteps stretched so fair a pathway! The illness, whatever it was--and neither Mr. Sheldon nor the portly and venerable physician whom he called in could find a name for it--crept upon the patient with stealthy and insidious steps. Dizziness, trembling, faintness; trembling, faintness, dizziness; the symptoms alternated day by day. Sometimes there was a respite of a few days; and Charlotte--the youthful, the sanguine, the happy--declared that her enemy had left her. "I am sure mamma is right, Di," she said on these occasions. "My nerves are the beginning and end of the mischief; and if I could get the better of my nerves, I should be as well as ever. I don't wonder that the idea of my symptoms makes mamma almost cross. You see, she has been accustomed to have the symptoms all to herself; and for me to plagiarise them, as it were, must seem quite an impertinence. For a strong young thing like me, you know, Di dear--who have only just broken myself of plunging downstairs two and three steps at a time, and plunging upstairs in the same vulgar manner--to intrude on mamma's shattered nerves, and pirate mamma's low spirits, is utterly absurd and abominable; so I have resolved to look my nerves straight in the face, and get the better of them." "My darling, you will get the better of them if you try," said Diana, who did at times beguile herself with the hope that her friend's ailments were mental rather than bodily. "I dare say your monotonous life has something to do with your altered health; you want change of scene, dear."
