He read it again : -- MY DEAR MR. WEST : As you have inferred from the postmark I am back at Truesdale ; we returned Wednesday . I have about despaired of seeing you here , at least of your own free will , so I have decided to kidnap you . Will you come to a coaching party Saturday afternoon -- or rather a brake party ? We shall start from our house , weather permitting , at four o'clock , and drive out to Oakwood , returning by moonlight . Please do n't let any stupid business interfere with your coming down and having a jolly time . Cordially , KATHERINE PORTER . Harvey slowly folded the note and replaced it in his pocket .
