His mouth set in a grim line. Silently, like a panther, he made one quick step to the desk, noiselessly opened a drawer, drew out his automatic. After that affair of the poisoned needle, he was taking no chances. Still in dead silence, he tiptoed to the door; then, flinging it suddenly open, he stood there, his weapon poised.

On the mat stood the most beautiful girl he had ever beheld. A veritable child of Faërie. She eyed him for a moment with a saucy smile; then with a pretty, roguish look of reproof shook a dainty forefinger at him.

'I believe you've forgotten me, Mr Gage!' she fluted with a mock severity which her eyes belied.

James stared at the paper dumbly. He was utterly perplexed. He had not had the slightest intention of writing anything like this. To begin with, it was a rule with him, and one which he never broke, to allow no girls to appear in his stories. Sinister landladies, yes, and naturally any amount of adventuresses with foreign accents, but never under any pretext what may be broadly described as girls. A detective story, he maintained, should have no heroine. Heroines only held up the action and tried to flirt with the hero when he should have been busy looking for clues, and then went and let the villain kidnap them by some childishly simple trick. In his writing, James was positively monastic.

And yet here was this creature with her saucy smile and her dainty forefinger horning in at the most important point in the story. It was uncanny.

He looked once more at his scenario. No, the scenario was all right.

In perfectly plain words it stated that what happened when the door opened was that a dying man fell in and after gasping, 'The beetle! Tell Scotland Yard that the blue beetle is—' expired on the hearth-rug, leaving Lester Gage not unnaturally somewhat mystified. Nothing whatever about any beautiful girls.

In a curious mood of irritation, James scratched out the offending passage, wrote in the necessary corrections and put the cover on the machine. It was at this point that he heard William whining.

The only blot on this paradise which James had so far been able to discover was the infernal dog, William. Belonging nominally to the gardener, on the very first morning he had adopted James by acclamation, and he maddened and infuriated James. He had a habit of coming and whining under the window when James was at work. The latter would ignore this as long as he could; then, when the thing became insupportable, would bound out of his chair, to see the animal standing on the gravel, gazing expectantly up at him with a stone in his mouth. William had a weak-minded passion for chasing stones; and on the first day James, in a rash spirit of camaraderie, had flung one for him. Since then James had thrown no more stones; but he had thrown any number of other solids, and the garden was littered with objects ranging from match boxes to a plaster statuette of the young Joseph prophesying before Pharaoh. And still William came and whined, an optimist to the last.

The whining, coming now at a moment when he felt irritable and unsettled, acted on James much as the scratching on the door had acted on Lester Gage. Silently, like a panther, he made one quick step to the mantelpiece, removed from it a china mug bearing the legend A Present From Clacton-on-Sea, and crept to the window.
