If Mrs. Inchbare was to be depended on, he must have gone to Craig Fernie instead of going to his appointed destination--and must, therefore, have arrived to visit his house and lands one day later than the day which he had originally set apart for that purpose. If this fact could be proved, on the testimony of a disinterested witness, the case against Arnold would be strengthened tenfold; and Lady Lundie might act on her discovery with something like a certainty that her information was to be relied on.
After a little consideration she decided on sending a messenger with a note of inquiry addressed to Arnold's steward. The apology she invented to excuse and account for the strangeness of the proposed question, referred it to a little family discussion as to the exact date of Arnold's arrival at his estate, and to a friendly wager in which the difference of opinion had ended. If the steward could state whether his employer had arrived on the fourteenth or on the fifteenth of August, that was all that would be wanted to decide the question in dispute.
Having written in those terms, Lady Lundie gave the necessary directions for having the note delivered at the earliest possible hour on the next morning; the messenger being ordered to make his way back to Windygates by the first return train on the same day.
This arranged, her ladyship was free to refresh herself with another dose of the red lavender draught, and to sleep the sleep of the just who close their eyes with the composing conviction that they have done their duty.
The events of the next day at Windygates succeeded each other in due course, as follows:
The post arrived, and brought no reply from Sir Patrick. Lady Lundie entered that incident on her mental register of debts owed by her brother-in-law--to be paid, with interest, when the day of reckoning came.
Next in order occurred the return of the messenger with the steward's answer.
He had referred to his Diary; and he had discovered that Mr. Brinkworth had written beforehand to announce his arrival at his estate for the fourteenth of August--but that he had not actually appeared until the fifteenth. The one discovery needed to substantiate Mrs. Inchbare's evidence being now in Lady Lundie's possession, she decided to allow another day to pass--on the chance that Sir Patrick might al ter his mind, and write to her.
If no letter arrived, and if nothing more was received from Blanche, she resolved to leave Windygates by the next morning's train, and to try the bold experiment of personal interference at Ham Farm.
The third in the succession of events was the appearance of the doctor to pay his professional visit.
