It was difficult to tell at first just what had happened, since the awning of the shop—it sold carpets, which explained the softness of our landing—had been crushed and ripped, and was being further demolished by a crew of eager rescuers. The men seemed somewhat disappointed at the absence of corpses, or even bloodshed (other than one of the outraged matrons, who had broken one of her glass bangles and nicked her arm on it), but the shopkeeper’s assistant, miraculously preserved by the chance of having been leaning against the wall, was first terrified, then ecstatic at the wails of the infant. He snatched up the child, startling up a new round of screeches, and patted him all over, unable to believe him whole. In familiar arms, the child’s sounds gave way to hiccoughing cries, and his tears and those of his father mingled down the man’s shirt-front.

When eventually the awning had been ripped from the front of the shop and we could step tentatively out onto the paving stones, it became immediately apparent how lucky we had been. Holmes’ quick reflexes had saved us from certain maiming, if not death outright, for the object that fell where we had been standing was probably three hundredweight of metal and wood.

“What is it?” I asked Holmes.

“I fear to ask,” he said, sounding more disgusted than troubled. I glanced over and saw that he was looking, not at the tangle of pipes and boards, but at his hands, smeared with some dark and noxious substance. He bent to appropriate a corner of the dusty awning cloth, scrubbing at his fingers.

“I meant the thing that fell.”

He ran his eyes over the object that had so nearly ended the eminent career of Sherlock Holmes, then lifted his gaze upwards, as half the people around us were doing. One dusty beam still clung to the rough mud-brick wall some twenty-five feet above, with a clear line of holes and dirt showing where the rest of the thing had been. A glance down the street showed a number of similar makeshift balconies, bits of wood and metal tacked onto the walls high above street level, all of them strung with drying laundry, decorated with petrol tins overflowing with flowers and herbs, furnished with cushions and rugs, and stacked high with various household goods not wanted inside. This one had linked to its apartment by way of a flimsy door, now opening onto thin air. And as we gazed upwards the door did open; the face of a horrified woman looked straight out, then down at us. She gaped down at the crowded street before belatedly realising that there were strangers looking back at her; she whipped her head-scarf across her face, gave us one last white-eyed look, and slammed the door, dislodging a few more scraps of timber and dust.
