Gimblet sighed. He could not help feeling that it was a pity Lord Ashiel had not earlier fallen into the habit of consulting him.
Still, he was bound to admit that though the stone group, regarded as a work of art, was altogether deplorable, the general effect of the erection, in its rectangular setting of forest, was excellent. The whole scene was one of peaceful and romantic beauty. Poets might have sat themselves down in that moist and shining spot; and, forgetful of the possibilities of rheumatism, found their muse inspiring beyond the ordinary.
Gimblet was at heart something of a poet, but he felt no inclination to communicate the feelings which the place and hour aroused in him to any of his companions; and it was in a silence which had in it something dimly foreboding that the party drew near to the statue.
In silence, Gimblet approached the great block of stone and laid his hand upon the projecting horn of the bull. Equally silently the two policemen had taken up positions at the end of the pedestal; the General stood behind them, alert and interested.
After a swift glance, which took in all these details, Gimblet turned the horn round in its socket.
The hidden door swung open, and there was a sound of muttered exclamations from the police and a loud oath from the General. Gimblet sprang round the corner of the pedestal, and there, as he expected, cowering in the mouth of the disclosed cavity, and looking, in his fury of fear and mortification, for all the world like some trapped vermin, crouched Lord Ashiel, glaring at his liberators with a rage that was hardly sane.
Beyond him, on the floor at the back, they could see the tin dispatch box standing open and empty.
The two policemen, acting on instructions previously given them, made one simultaneous grab at the young man and dragged him into the open with several seconds to spare before the door slammed to again, in obedience to the invisible mechanism that controlled it. They set him on his legs on the wet turf, and stood, one on each side of him, a retaining hand still resting on either arm.
For a moment Mark gazed from the General to the detective, his eyes full of hatred. Then he controlled himself with an effort, and when he spoke it was with a forced lightness of manner.
"I have to thank you for letting me out," he said. "The air in there was getting terrible." He paused, and filled his lungs ostentatiously, but no one answered him. Losing something of his assumed calmness, he went on, uneasily: "I just thought I'd come along and see if there was any truth in Mr. Gimblet's story; and I was quite right to doubt it, since there isn't. He's not quite as clever as he thinks, for he was as positive as you like that my uncle's will was hidden here, but as a matter of fact it's not, as I was taking the trouble to make sure when that cursed statue shut me in. There's nothing in it of any sort except an empty tin box."
