"Dear Tims,—I am afraid you will not find me to-morrow afternoon, as I am going out of town. But do go to tea with Tony, who is just back from the sea and looking bonny. He is such a darling! I always mind leaving him, although of course I am not his mother. Oh, dear, I am so sleepy, I hardly know what I am saying. Good-bye, Tims, dear. I am very glad you are so happy with that nice Mr. Fitzalan of yours.

Yours,

M. B. S."

So far the note, although bearing signs of haste, was in Mildred's usual clear handwriting; but there was a postscript scrawled crookedly across the inner sides of the sheet and prefixed by several flourishes:

"Meet me at Paddington 4.30 train to-morrow. Meet me.

M."

Another flourish followed.

The note found Tims at the laboratory, which she had not intended leaving till half-past four. But the perplexing nature of the postscript, conflicting as it did with the body of the letter, made her the more inclined to obey its direction.

She arrived at Paddington in good time and soon caught sight of Mildred, although for the tenth part of a second she hesitated in identifying her; for Mildred seldom wore black, although she looked well in it. To-day she was dressed in a long, black silk wrap—which, gathered about her slender figure by a ribbon, concealed her whole dress—and wore a long, black lace veil which might have baffled the eyes of a mere acquaintance. Tims could not fail to recognize that willowy figure, with its rare grace of motion, that amber hair, those turquoise-blue eyes that gleamed through the swathing veil with a restless brilliancy unusual even in them. With disordered dress and hat on one side, Tims hastened after Mildred.

"So here you are!" she exclaimed; "that's all right! I managed to come, you see, though it's been a bit of a rush."

Mildred looked around at her, astonished, possibly dismayed; but the veil acted as a mask.

"Well, this is a surprise, Tims! What on earth brought you here? Is anything the matter?"

"Just what I wanted to know. Why are you in black? Going to a funeral?"
