"What on earth can she have to say, when she hates writing so," Susy mused.
She broke open the envelope, and four or five stamped and sealed letters fell from it. All were addressed, in Ellie's hand, to Nelson Vanderlyn Esqre; and in the corner of each was faintly pencilled a number and a date: one, two, three, four--with a week's interval between the dates.
"Goodness--" gasped Susy, understanding.
She had dropped into an armchair near the table, and for a long time she sat staring at the numbered letters. A sheet of paper covered with Ellie's writing had fluttered out among them, but she let it lie; she knew so well what it would say! She knew all about her friend, of course; except poor old Nelson, who didn't, But she had never imagined that Ellie would dare to use her in this way. It was unbelievable... she had never pictured anything so vile.... The blood rushed to her face, and she sprang up angrily, half minded to tear the letters in bits and throw them all into the fire.
She heard her husband's knock on the door between their rooms, and swept the dangerous packet under the blotting-book.
"Oh, go away, please, there's a dear," she called out; "I haven't finished unpacking, and everything's in such a mess." Gathering up Nick's papers and letters, she ran across the room and thrust them through the door. "Here's something to keep you quiet," she laughed, shining in on him an instant from the threshold.
She turned back feeling weak with shame. Ellie's letter lay on the floor: reluctantly she stooped to pick it up, and one by one the expected phrases sprang out at her.
"One good turn deserves another.... Of course you and Nick are welcome to stay all summer.... There won't be a particle of expense for you--the servants have orders.... If you'll just be an angel and post these letters yourself.... It's been my only chance for such an age; when we meet I'll explain everything. And in a month at latest I'll be back to fetch Clarissa...."
Susy lifted the letter to the lamp to be sure she had read aright. To fetch Clarissa! Then Ellie's child was here? Here, under the roof with them, left to their care? She read on, raging. "She's so delighted, poor darling, to know you're coming. I've had to sack her beastly governess for impertinence, and if it weren't for you she'd be all alone with a lot of servants I don't much trust. So for pity's sake be good to my child, and forgive me for leaving her. She thinks I've gone to take a cure; and she knows she's not to tell her Daddy that I'm away, because it would only worry him if he thought I was ill. She's perfectly to be trusted; you'll see what a clever angel she is...." And then, at the bottom of the page, in a last slanting postscript: "Susy darling, if you've ever owed me anything in the way of kindness, you won't, on your sacred honour, say a word of this to any one, even to Nick. And I know I can count on you to rub out the numbers."
