I may add that the professional watchers in the island were not of course in the secret of Mr. Hobhouse's identity, and therefore could not report to him directly anything they might see or suspect. But if they did see or suspect anything he would very quickly be informed through another source. However Commander Whiteclett based no great hopes on the possibility of catching our wily enemy out by means of a palpable man in uniform, and Mr. H. had been instructed to act exactly as though he were alone on the job.
One of his earliest expeditions was made to the site of a prehistoric building in the near vicinity of the Scollays' farm. At least there was a grassy knoll visible which Mr. H.'s expert eye at once pronounced to be worthy of very careful inspection, and in order to confirm his theories he decided to visit the farm to make enquiry as to any possible traditions regarding it.
He passed round the knoll with this purpose, to discover that he was no longer meditating alone. A familiar figure confronted him, with dark staring eyes, gaping mouth, and stubby beard; my old friend Jock. For a moment there returned that feeling of stage fright. Next to the Rendalls, the Scollay household, and particularly Jock, had seen and conversed most often with the mysterious Merton. Jock was only an idiot, but where reason is lacking instinct is apt to be strong, and instinct might distinguish an old acquaintance through all my disguise. Anyhow, rightly or wrongly, I felt that this was another delicate moment.
"Good-day, my good fellow. Good-day to you!" said the friendly Mr.
Hobhouse. "A little better weather to-day!"
The surprise of the affable gentleman at getting only a grunt in reply, his air of gradual comprehension, and then of friendly sympathy, were acted for all they were worth. And to my vast relief, Jock showed no glimmer of recognition of the young man with the revolver.
"Do you know who lives at that farm?" enquired Mr. Hobhouse speaking very distinctly. "Tolly, you say? Oh, jolly? Yes, very jolly! Ha, ha! Good-bye, my lad, good-bye to you!"
Jock's hoot of laughter was answered by Mr. Hobhouse's giggle, and they set off down to the farm, the antiquary in front limping rather more markedly than usual, and the idiot rambling behind.
The visit to the Scollays was a distinct success, so far as establishing the personality of Mr. Thomas Sylvester Hobhouse went. At first they looked at him with an obvious suspicion and replied to his questions with a reticence that gave him a few uneasy moments. But in ten minutes his indefatigable friendliness had conquered the household and he knew that he was safe to visit that knoll whenever the fancy took him. Peter senior told him a long story about the fairies who were seen dancing round the knoll in his father's time, and though his family were evidently a little distressed by his reference to anything so unfashionable, and Jock hooted several times, their visitor exhibited the liveliest interest and put the tale religiously down in his note book.
This was all that could be done at the moment; the establishment of a perfectly harmless reputation and of a natural reason for visiting that particular place at odd times. Mr. Hobhouse obtained permission to do a little digging there if he desired it, and parted with the family on the best of terms.
"Slow work!" he said to himself as he struck out for home, with his limp rapidly vanishing. "But what the devil else can one do? What is there definite to take hold of?"
