“Yes, if you think it wise?”
“It’s not wise, but I think we must risk it. You’re not known here. But come alone; Benson shouldn’t attempt it.”
“Right. What time?”
“What about nine? I often work in the evenings, and I’m never disturbed. Come round to my study window and I shall be there. Tap lightly. The window is on the right-hand side of the house as you come up the drive, the fourth from the corner. You can slip round to it in the shadow of the bushes, and keep on the grass the whole time.”
“Right. Nine o’clock, then.”
The switch of the telephone clicked, and presently Willis saw Archer reappear in his office.
The inspector was disappointed. He had hoped that the conspirators would have completed their plans over the telephone, and that he would have had nothing to do but listen to what they arranged. Now he saw that if he were to gain the information he required, it would mean a vast deal more trouble, and perhaps danger as well.
He felt that at all costs he must be present at the interview in Archer’s study, but the more he thought about it, the more difficult the accomplishment of this seemed. He was ignorant of the plan of the house, or what hiding-places, if any, there might be in the study, nor could he think of any scheme by which he could gain admittance. Further, there was but little time in which to make inquiries or arrangements, as he could not leave his present retreat until dark, or say six o’clock. He saw the problem would be one of the most difficult he had ever faced.
But the need for solving it was paramount, and when darkness had set in he let himself out of the cottage and walked the mile or more to Archer’s residence. It was a big square block of a house, approached by a short winding drive, on each side of which was a border of rhododendrons. The porch was in front, and the group of windows to the left of it were lighted up—the dining-room, Willis imagined. He followed the directions given to Beamish and moved round to the right, keeping well in the shadow of the shrubs. The third and fourth windows from the corner on the right side were also lighted up, and the inspector crept silently up and peeped over the sill. The blinds were drawn down, but that on the third window was not quite pulled to the bottom, and through the narrow slit remaining he could see into the room.
It was empty, but evidently only for the time being, as a cheerful fire burned in the grate. Furnished as a study, everything bore the impress of wealth and culture. By looking from each end of the slot in turn, nearly all the floor area and more than half of the walls became visible, and a glance showed the inspector that nowhere in his purview was there anything behind which he might conceal himself, supposing he could obtain admission.
