As Foyle passed on, he observed a man hurrying towards him and recognised Malley. Abruptly the superintendent turned his back and, leaning his arms upon a low stone wall, seemed lost in contemplation of a little churchyard. When the divisional inspector had passed on, Foyle resumed his walk.
It cost him some little trouble to find the road in which the motor-car had been left derelict. The sodden earth still retained wheel tracks, and it needed but a glance to show that the car had been removed but a few hours before. He walked on till he came to the
place where Green had found the strip of brown cloth, which was fairly plain to find, for the footsteps of Green and the other police officers when they followed the trail ceased there as Grell's had done.
Here he drew a small pocket-compass from his waistcoat pocket, and pressing a spring released the needle. As it came to rest he thrust aside the hazel bushes and plunged in among the undergrowth. Now and again he consulted the compass as he walked leisurely forward, wet branches brushing his face and whipping at his clothes. For the brief portion of the way a keeper's path facilitated his progress, but at last he was forced to abandon this and return to the wilder portion of the wood. He was making a detour which he hoped would lead him to the back of Dalehurst Grange.
At last he could see a clear space ahead of him, and in a little, sinking on his knees on a bank, was peering downhill to an old-fashioned, Jacobean manor-house, from whose chimney smoke was lazily wreathing upward. Between him and the house a meadow sloped for a hundred yards, and the back of the house was bounded by an irregular orchard.
"Pity I didn't think to bring a pair of field-glasses," muttered Foyle, as his eyes swept the place. "I can't tell how those mullioned windows are protected. Well, I may as well make myself comfortable, I suppose."
A little search rewarded him with a great oak tree, and in the fork of a branch twenty feet high he found an easy seat from which he could watch the house without any great risk of being seen himself. Immobile as a statue, he remained till long after dusk had fallen and a steady light appeared at one of the windows.
It was, in fact, ten o'clock, and the light had disappeared when he dropped quietly to earth and, with quick footsteps, began to cross the meadow to the orchard.
Under the fruit trees the detective moved slower and held his stick before him, softly tapping the ground as though he were blind. He had not taken half-a-dozen steps before the stick touched something stretched about a foot from the ground. Stooping, he groped in the darkness.
"A cord," he muttered. "Now I wonder if that is merely a precaution against burglars or——" and, stepping over the obstacle, he went on cautiously feeling his way. Twice more he found cords stretched across the grass, so that an unwary intruder might be tripped up, but his caution enabled him to avoid them.
