“I must be going,” he replied. “You have letters to write I know, and if Ella is to be shut-up at her lessons all the afternoon, the prospect is not lively.” Then Ella heard them leave the room.

With a rush there came over her the realisation of what she had been doing—“Listening!” Her face grew scarlet with shame but not for long.

“I could not have helped it,” she thought with a kind of defiance. “Their very first words were about me: I should never have known the truth had I interrupted them. And at all costs it was best to know it. Now I need have no hesitation. I will not stay another night here—they shall never be troubled by me again.”

Her face glowed as she recalled some of the expressions she had overheard. Then again she felt perplexed at certain allusions she could not explain. What did Madelene mean by speaking of “financial” complications?

“We are all three sisters; it isn’t as if one of us were a son,” she thought. “Even if most is to go to Madelene as the eldest, papa is certainly rich enough to provide well for Ermine and me too. Not that I want their money—I shall let them see that. I don’t in the least mind earning my own living, and I am sure I am able to do so. I should thank papa, I suppose, for having made me work hard since I have been here. It is as if he had foreseen it.” Then her thoughts took another turn. Who was “Omar”? Some one that Madelene was to marry, or would have married already, it appeared, but for her, Ella’s, unlucky advent.

“Everything of course, everything unfortunate is put upon my shoulders,” she reflected bitterly. “Still Madelene means to be good and unselfish, I do believe. She shall not be sacrificed to me. And when she is married to this Mr Omar, whoever he is, and Ermine to Sir Philip, I don’t think they will have much to reproach me with, ‘sore subject’ though I am.”

She sat still for a moment or two till she felt a little more collected. Then she crept quietly up stairs to her own room, locked the door by way of precaution and set to work.

All her belongings were together and in neat order. “It will be quite easy for any one to pack everything up,” she thought. Then she dressed herself in her warmest clothes, put a few things into a bag not too heavy for her to carry, and when all was ready, sat down to write a few words, which, as is the fashion of heroines in such circumstances, she fastened conspicuously to her toilet pincushion. The note was addressed to Miss St Quentin and contained these words:—

“I overheard what you and Sir Philip were talking about in the drawing-room; I know it was dishonourable to listen, but I could not help it, after the first. It is not my fault that I have been such a sore trouble to you hitherto, but it would be if I stayed here, knowing better now. I will write to you when my plans are settled, but it isn’t any use sending after me, as I am not going anywhere you know. I hope you will be very happy—and I hope Ermine will be very happy too. Please tell papa I see now how wise it was to make me go on with my lessons.

“Your affectionate sister,—
