John Gilman made the suggestion that they should let the matter rest until Eileen explained about it. Then Linda spoke very quietly, but with considerable finality in her tone.

“No,” she said, “I know that Eileen had no source of private income. Mother used to mention that she had some wealthy relatives in San Francisco, but they didn’t approve of her marriage to what they called a ‘poor doctor,’ and she would never accept, or allow us to accept, anything from them. They never came to see us and we never went to see them. Eileen knows no more about them than I do. We will work upon the supposition that everything that is here belonged to Father. Set aside to Eileen’s credit the usual amount for housekeeping expenses. Turn the private account in with the remainder. Start two new bank books, one for Eileen and one for me. Divide the surplus each month exactly in halves. And I believe this is the proper time for the bank to turn over to me a certain key, specified by my father as having been left in your possession to be delivered to me on my coming of age.”

With the key in her possession, Linda and John Gilman left the bank. As they stood for a moment in front of the building, Gilman removed his hat and ran his hands through his hair as if it were irritating his head.

“Linda,” he said in a deeply wistful tone, “I don’t understand this. Why shouldn’t Eileen have come to-day as she agreed? What is there about this that is not according to law and honour and the plain, simple rights of the case?”

“I don’t know,” said Linda; “but there is something we don’t understand about it. And I am going to ask you, John, as my guardian, closing up my affairs to-day, to go home with me to be present when I open the little hidden door I found at the back of a library shelf when I was disposing of Daddy’s technical books. There was a slip of paper at the edge of it specifying that the key was in possession of the Consolidated Bank and was to be delivered to me, in the event of Daddy’s passing, on my coming of age. I have the key, but I would like to have you with me, and Eileen if she is in the house, when I open that door. I don’t know what is behind it, but there’s a certain feeling that always has been strong in my heart and it never was so strong as it is at this minute.”

So they boarded the street car and ran out to Lilac Valley. When Katy admitted them Linda put her arm around her and kissed her. She could see that the house was freshly swept and beautifully decorated with flowers, and her trained nostrils could scent whiffs of delicious odours from food of which she was specially fond. In all her world Katy was the one person who was celebrating her birthday. She seemed rather surprised when Linda and Gilman came in together.

“Where is Eileen?” inquired Linda.

“She must have made some new friends,” said Katy. “About four o’clock, the biggest car that ever roared down this street rolled up, and the biggest man and woman that I ever see came puffin’ and pantin’ in. Miss Eileen did not tell me where she was goin’ or when she would be back, but I know it won’t be the night, because she took her little dressin’ case with her. Belike it’s another of them trips to Riverside or Pasadena.”

“Very likely,” said Linda quietly. “Katy, can you spare a few minutes?”

“No, lambie, I jist can’t,” said Katy, “because a young person that’s the apple of me eye is havin’ a birthday the day and I have got me custard cake in the oven and the custard is in the makin’, and after Miss Eileen went and I didn’t see no chance for nothin’ special, I jist happened to look out, one of the ways ye do things unbeknownst to yourself, and there stood Mr. Pater Morrison moonin’ over the ‘graveyard’, like he called it, and it was lookin’ like seein’ graves he was, and I jist took the bull by the horns, and I sings out to him and I says: ‘Mr. Pater Morrison, it’s a good friend ye were to the young missus when ye engineered her skylight and her beautiful fireplace, and this bein’ her birthday, I’m takin’ the liberty to ask ye to come to dinner and help me celebrate.’ And he said he would run up to the garage and get into his raygimentals, whatever them might be, and he would be here at six o’clock. So ye got a guest for dinner, and if the custard’s scorched and the cake’s flat, it’s up to ye for kapin’ me here to tell ye all this.”
