No one entering the room for the first time could fail to remark upon it; in spite of its comparatively insignificant size it dominated the whole room like an idol in a temple.

George Abbershaw was struck by it as soon as he came in, and instantly the feeling of apprehension which had annoyed his prosaic soul so much in the other room returned, and he glanced round him sharply, seeking either reassurance or confirmation, he hardly knew which.

The house-party which had seemed so large round the dinner-table now looked amazingly small in this cathedral of a room.

Colonel Coombe had been wheeled into a corner just out of the firelight by a man-servant, and the old invalid now sat smiling benignly on the group of young people in the body of the room. Gideon and the man with the expressionless face sat one on either side of him, while a grey-haired, sallow-faced man whom Abbershaw understood was a Dr White Whitby, the Colonel’s private attendant, hovered about them in nervous solicitude for his patient.

On closer inspection Gideon and the man who looked like Beethoven proved to be even more unattractive than Abbershaw had supposed from his first somewhat cursory glance.

The rest of the party was in high spirits. Anne Edgeware was illustrating the striking contrast between Victorian clothes and modern manners, and her vivacious air and somewhat outrageous conversation made her the centre of a laughing group. Wyatt Petrie stood amongst his guests, a graceful, lazy figure, and his well-modulated voice and slow laugh sounded pleasant and reassuring in the forbidding room.

It was Anne who first brought up the subject of the dagger, as someone was bound to do.

‘What a perfectly revolting thing, Wyatt,’ she said, pointing at it. ‘I’ve been trying not to mention it ever since I came in here. I should toast your muffins with something else, my dear.’

‘Ssh!’ Wyatt turned to her with mock solemnity. ‘You mustn’t speak disrespectfully of the Black Dudley Dagger. The ghosts of a hundred dead Petries will haunt you out of sheer outraged family pride if you do.’

The words were spoken lightly, and his voice had lost none of its quiet suavity, but whether it was the effect of the dagger itself or that of the ghostly old house upon the guests none could tell, but the girl’s flippancy died away and she laughed nervously.
