He put through his business there very quickly and returned to Lochearnhead by the earliest possible train. During the whole journey he was racking his brains as to how and where he could discover the address of the old servant of whom Malcolm had spoken. He knew Isla’s ways, and he was aware that it had always been her delight when in London to look up any of her own folk who were settled there. He ran over in his memory the servants at Achree with whom he had been familiar, but he could not fix his mind on anyone in particular. Diarmid, however, who had been with the Mackinnons for nearly thirty years, would surely be able to help him. He would go to Diarmid. His bicycle had been left at the station, because the train had offered a quicker way of getting over the heavy roads to Callander. He now took it out and rode swiftly down the hill to Lochearn and up Glenogle towards Creagh. Neil had all the swift impetuosity of the Celt in his blood, and he did not let the grass grow under his feet. He was fortunate, however, in obtaining the information he desired about half way up, at the farm-house of Darrach, where he came upon Elspeth Maclure taking her washing down off the lines in the front garden. He swung himself off his machine, set it against the drystone dyke, and pushed open the little gate. Elspeth, surprised and pleased by this little attention, hastened to ask him into the house. He thanked her, but declined. "I am seeking information, Mrs. Maclure. I was on my way to Creagh to see Diarmid, but perhaps you will do. Do you remember the name of an old servant of the Mackinnons who married in London and settled somewhere in the neighbourhood of the Edgeware Road?" A curious flicker crossed Elspeth’s eager face. "You mean Agnes Fraser that was under housemaid at Achree when I was upper of three, do ye, Maister Drummond?" "I suppose I do if the description answers," he said with a laugh. "But I don’t know her name." "She lives at 18 Cromer Street, Edgeware Road, sir," answered Elspeth. "If ye’ll just come intil the hoose I’ll write it doon." "Here you are," said Neil, drawing out a notebook and a pencil. "18 Cromer Street, Edgeware Road. Thank you very much. That saves me that stiff pull to Creagh, and the roads are heavy to-day. I was glad to leave my machine at the station and take a handy train to Callander. Maclure and all the young folks well, I hope?" "Yes, sir, thank you," said Elspeth, but the odd, eager expression did not leave her face as she followed the Laird of Garrion to the gate. "I had a letter from Mrs. Fraser not so long ago, Maister Drummond." "You had--eh? And what was her news?" "She said she had had Miss Mackinnon stoppin’ at her hoose. That was aboot a month ago." "Do you think she is there still?" asked Neil with apparent carelessness, though his hand as he stooped to his bicycle trembled a little.
