In Derek's own room she sat down at the desk where, six months ago, she had arranged his letters on the night when he had returned from South America. She had no time to indulge in memories, but a tremor shot through her frame as she took up the pen and wrote on a sheet of paper which he had already headed with a date:
"I have bad news for you, but I hope I may be in time to keep it from being worse. I have reason to think that Dorothea has gone to Lakefield to be married there to Carli Wappinger. Should there be any mistake you will forgive me for disturbing you; but I think it well to be prepared for extreme possibilities. I am, therefore, going to Lakefield now--at once. A train at seven-fifteen will get there a little after nine. There are other trains through the evening, the latest being at five minutes after ten. Should this reach you in time to enable you to take one of them, you will be wise to do so; but in case it may be too late, you may count on me to do all that can be done. Let some one be ready to answer the telephone all night. I shall communicate with the house from the Bay Tree Inn. I must ask you again to forgive me if I am interfering rashly in your affairs, but you can understand that I have no time to take counsel or reflect.
[Illustration: DRAWN BY FRANK CRAIG HAVING MADE A COPY OF THIS LETTER, SHE CALLED SIMMONS AND FULTON AND GAVE THEM THEIR INSTRUCTIONS]
Having made a copy of this letter, she called Simmons and Fulton and gave them their instructions. There had been an accident, she said, of which she had been able to get only imperfect information, but it seemed possible that Miss Dorothea was involved in it. She herself was hurrying to Lakefield, and it would be Simmons' task to find Mr. Pruyn in time for him to catch the ten-five train, at latest. He was to pack two valises with all that Mr. Pruyn could require for a change. He was to take one of the two letters, and one of the two valises, and go from place to place, until he tracked his master down. Fulton was to say nothing to alarm the other servants, merely informing Miss Dorothea's maid that the young lady was absent for the night and that Mrs. Eveleth was with her. He would take charge of the second letter and the second valise, in case Mr. Pruyn should return to the house before Simmons could find him. The important charge of the telephone was also to be in Fulton's trust, and he was to answer all calls through the night. In concluding her directions Diane acknowledged her relief in having two lieutenants on whose silence, energy, and tact she could so thoroughly depend. She committed the matter to their hands not merely as to Mr. Pruyn's butler and valet, but as to his trusted friends, and in that capacity she was sure they would do their duty and hold their tongues.
