At the back of the house, the drive continued to a carriage house where my father had kept his motorcars. Holmes went on, standing on his toes to peer through the high windows, then came away. “Nothing there,” he said, but of course there was nothing inside; my father's last motor had gone off a cliff and exploded in a freshly filled tank of petrol.

We stood looking at the impenetrable garden in back of the house. “Do you want to push through that?” I asked him.

“As there's no particular urgency, perhaps we ought to play the Livingstone-in-blackest-Africa rôle when we've had a chance to don thorn-proof outer garments.”

“And snake-proof boots,” I added. As we turned back towards the front, I shook my head in disgust. “The garden must have received some rudimentary attention, but it doesn't appear as if anyone has been inside the house for years. I thought there was an arrangement to keep the place up.”

“I'd have thought it desirable, from a property manager's point of view. Undoubtedly your Mr Norbert will know why.”

“He's got some explaining to do; no house should be allowed to get into this condition. It's a wonder the neighbours haven't complained.”

“Perhaps they have,” Holmes commented—but not, as I first thought, about the shocking condition of the paint. A motorcar had pulled up in front of the gate, and now I heard two doors slam shut as a pair of powerful torches probed the drive.

“You there,” shouted a voice whose tones would carry the same authority the world around. “Come out here at once.”

“The constabulary have arrived,” Holmes said unnecessarily, and together we moved to obey the command.

Our dress, our demeanour, and our accents soon had the torch-light diverted from our faces into a kinder illumination, and our claim to be the house's concerned but keyless owners was not instantly discounted. One of the policemen even came up with an orange crate from somewhere, so I could climb with dignity back over the fence. The last shred of suspicion fluttered away after we had been taken to the hotel and been recognised by the doorman. We thanked the two policemen for their concern over the property, and then I put to them the question that Holmes had raised mere moments before they had arrived.

“Before you go, may I ask? Which of the neighbours reported our presence? I'd like to thank them for their concern, don't you know.”

The two burly men looked at each other; the older one shrugged. “It's the old dame across the street. She's kinda taken the house under her wing—'phones the station every so often to have us chase kids out before they can get into mischief.”

“I do understand. Sleepless old lady with nothing better to do. She'll be disappointed we weren't stealing the doorknobs.”
