The door, however, opened to admit an elderly West Indian, of so humble and inoffensive an appearance that the hearts of the two detectives sank into their boots. Anything less murderous could scarcely be imagined, as he stood blinking nervously at them from behind a pair of steel-rimmed spectacles, the frames of which had at one time been broken and bound with twine.

The Rev. Hallelujah Dawson was undoubtedly a man of colour. He had the pleasant, slightly aquiline features and brown-olive skin of the Polynesian. His hair was scanty and greyish—not woolly, but closely curled. His stooping shoulders were clad in a threadbare clerical coat. His black eyes, yellow about the whites and slightly protruding, rolled amiably at them, and his smile was open and frank.

“You asked to see me?” he began, in perfect English, but with the soft native intonation. “I think I have not the pleasure—?”

“How do you do, Mr. Dawson? Yes. We are—er—makin’ certain inquiries—er—in connection with the family of the Dawsons of Crofton in Warwickshire, and it has been suggested that you might be able to enlighten us, what? as to their West Indian connections—if you would be so good.”

“Ah, yes!” The old man drew himself up slightly. “I am myself—in a way—a descendant of the family. Won’t you sit down?”

“Thank you. We thought you might be.”

“You do not come from Miss Whittaker?”

There was something eager, yet defensive in the tone. Wimsey, not quite knowing what was behind it, chose the discreeter part.

“Oh, no. We are—preparin’ a work on County Families, don’t you know. Tombstones and genealogies and that sort of thing.”

“Oh!—yes—I hoped perhaps—” The mild tones died away in a sigh. “But I shall be very happy to help you in any way.”
