"Are you a clever doctor?" she demanded.

"I have been told so," I remarked, suppressing a smile.

"Then come inside and see what you can do for my mistress."

"Is your mistress Mrs. MacDerry?"

"Aye," she nodded. "It's herself." Without another word she turned and led the way up the narrow path, apparently taking it for granted that I would follow.

"What's the matter with your mistress?" I asked as I reached the door.

"If you're clever you'll find out for yourself," she remarked tersely, and again I suppressed a smile. An uncompromising handmaiden this....

She left me alone in the room which in such houses is generally alluded to as the parlour, and while I waited I stared about me idly. And as I stared my vague curiosity gave way to acute surprise. Generally the furniture in such rooms must be seen to be believed: stuffed birds in glass domes, and beaded ornaments of incredible design meet one at every step. And should one lift one's eyes in a moment of panic to the walls, innumerable photographs of wedding groups leap at you in mute protest. But there was nothing of that sort in this room....

Everything was in the most exquisite taste, from the bric-à-brac on a beautiful inlaid table, to the baby Grand standing in the corner. I glanced at some of the pictures, and my surprise changed to amazement. Three at least were genuine Corots.... And the next thing that caught my eye were half a dozen pieces of Sèvres....

"Will you come this way, please?" The woman's harsh voice from the door interrupted my inspection, and I followed her slowly up the stairs.
