From where she stood she surveyed the lie of the land.

It was simple enough. The house stood away from the road, exactly as the Saint had described it, in its own rather spacious grounds, and there was not a light showing anywhere. To find it almost without hesitation had been easy enough. The studio in Chelsea had been amply equipped for the simple preparation of any such excursion. There had been a telephone directory from which to discover Cullis's address, a street directory in which to find the exact location of his house, and a large-scale map from which to read the most straightforward approach. These three reference alone would have been material enough even for anyone less accustomed to rapid and concise thinking than Jill Trelawney, and the investigation had not taken her more than three minutes. After which she had a faultlessly photographic memory in which to hold the results of that investigation in their place. She remembered that at the back of the house there was a piece of land on which no buildings were marked on the map; but under the faint light of a half-fledged moon she could see the dark masses of scaffolding and unfinished walls in the background, and marked down that terrain as a convenient avenue of escape in case of need.

In her own way she had had her fair share of luck. The last patrolling policeman she had seen had been near Baker Street, and the road in which she now stood was deserted. Knowing the habits of policemen on night patrol, her keen eyes probed deep into every patch of shadow around her; but there was no one there.

She turned off the road and slipped noiselessly over the low gate into the front garden.

The Saint had kindly warned her about the alarms on the ground-floor windows. He had also been good enough to explain his method of approach by way of the drain pipe. But she did not feel confident to cope with drain pipes. Ivy was easier, if more risky and more noisy and at the back of the house there was a patch of ivy running to a very convenient window on the first floor.

She went up as if she had been born in a circus.

The ledge of the window came easily under her feet, and she found that the latch was not even fastened. She slid up the lower sash with the merest rustle of sound, and lowered herself warily over the sill.

The darkness inside was impenetrable, but that meant nothing to her. She moved through the room inch by inch, with her fingers weaving sensitively in front of her, and reached the door in utter silence after several seconds. Not until she was out on the landing, with the door closed again behind her, did she dare to switch on her tiny electric torch.

By its light she found the stairs and went down them into the hall. Crossing the hall, she opened a door on the far side and cautiously closed it again behind her. Then she went over to a window, located the alarms with her torch, disconnected them, and opened the window wide, drawing the heavy curtains again when she had finished.

The beam of her torch filtered through the darkness, flickering over every part of the room. A massive safe that stood in one corner she ignored without a moment's hesitation — Cullis would never have taken the risk of keeping anything incriminating in a place which would be the obvious objective of any chance intruder. She went over the bookcase shelf by shelf, shifting the books one by one and searching expertly for a dummy row or a panel concealed in the back of the case, but she found nothing The pictures on the walls detained her for very little longer: there was nothing concealed behind any of them. And then she lighted another cigarette and looked around her with a rather rueful frown.
