Ten feet, at the most. On either side of the balcony rose ornately carved columns of painted wood. A half-moon arch spanned them an arm's length down, completing the fancy frame. With a final glance at the house guard, who had not moved, and whose spear did not seem in danger of clattering to the flagstones at any moment, Crokus slowly lowered himself down the wall.

His moccasins' pitch gripped the eaves with snug assurance. There were plenty of handholds, as the carver had cut deep into the hardwood, and sun, rain and wind had weathered the paint. He descended along one of the columns until his feet touched the balcony's handrail where it abutted the wall. A moment later he crouched on the glazed tiles in the shadow of a wrought-iron table and pillowed chair.

No light leaked between the shutters of the sliding door. Two soft steps brought him next to it. A moment's examination identified the style of the latch's lock. Crokus withdrew a fine-toothed saw and set to work. The sound the tool made was minimal, no more than the shivering of a locust's leg. A fine tool, rare and probably expensive. Crokus was fortunate in having an uncle who dabbled in alchemy and had need of such magically hardened tools when constructing his bizarre condensing and filtering mechanisms. Better yet, an absent-minded uncle prone to misplacing things.

Twenty minutes later the saw's teeth snipped the last restraining bolt. He returned the tool to his harness, wiped the sweat from his hands, then nudged the door open.

Crokus poked his head into the room. In the grey dimness he saw a large four-poster bed a few feet to his left, its headboard against the outer wall. Mosquito netting descended around it, ending in piled heaps on the floor. From within came the even breaths of someone deep in sleep. The room was redolent of expensive perfume, something spicy and probably from Callows.

Immediately across from him were two doors, one ajar and leading into a bathing chamber; the other a formidable barrier of banded oak sporting an enormous lock. Against the wall to his right stood a clothes cupboard and a makeup stand over which stood three polished silver mirrors hinged together. The centre one rose flush on the wall, the outer two angled on to the tabletop to provide an infinity of admiring visages.

Crokus turned sideways and edged into the room. He rose slowly and stretched, relieving his muscles of the tension that had held them for the past half-hour. He swung his gaze to the makeup stand, then tiptoed towards it.

The D'Arle estate was third from the summit of Old K'rul's Avenue, which climbed the first of the inner city's hills to a circular court tangled with weeds and irregular, half-buried dolmens. Opposite the court rose K'rul Temple, its ancient stones latticed with cracks and entombed in moss.
