From the entrance to Mrs. Fenimore’s round to the by-road which was the direct approach to Redgrave’s bungalow would be a walk of some ten minutes.  Hugh had his reasons for not taking this direction.  Having dismissed his cab, he entered by the lodge-gate, and walked up the drive, moving quickly, and with a lighter step than was natural to him.  When he came within view of the house, he turned aside, and made his way over the grass, in the deep shadow of leafy lime-trees, until the illumined windows were again hidden from him.  He had seen no one, and heard no sound.  A path which skirted the gardens would bring him in a few minutes to Redgrave’s abode; this he found and followed.

The bungalow was built in a corner of the park where previously had stood a gardener’s cottage; round about it grew a few old trees, and on two sides spread a shrubbery, sheltering the newly-made lawn and flower-beds.  Here it was very dark; Hugh advanced cautiously, stopping now and then to listen.  He reached a point where the front of the house became visible.  A light shone at the door, but there was no movement, and Hugh could hear only his own hard breathing.

He kept behind the laurels, and made a half-circuit of the house.  On passing to the farther side, he would come within view of those windows which opened so conveniently, as Mrs. Maskell had said —­ the windows of Redgrave’s sitting-room, drawing-room, study, or whatever he called it.  To this end it was necessary to quit the cover of the shrubs and cross a lawn.  As he stepped on to the mown grass, his ear caught a sound, the sound of talking in a subdued tone; it came, he thought, from that side of the building which he could not yet see.  A few quick silent steps, and this conjecture became a certainty:  someone was talking within a few yards of him, just round the obstructing corner, and he felt sure the voice was Redgrave’s.  It paused; another voice made reply, but in so low a murmur that its accents were not to be recognised.  That it was the voice of a woman the listener had no doubt.  Spurred by a choking anguish, he moved forward.  He saw two figures standing in a dim light from the window-door —­ a man and a woman; the man bareheaded, his companion in outdoor clothing.  At the same moment he himself was perceived.  He heard a hurried ‘Go in!’ and at once the woman disappeared.

Face to face with Redgrave, he looked at the window; but the curtain which dulled the light from within concealed everything.

‘Who was that?’

‘Why —­ Carnaby?  What the deuce ——?’

‘Who was that?’

‘Who? —­ what do you mean?’

Carnaby took a step; Redgrave laid an arresting hand upon him.  There needed but this touch.  In frenzied wrath, yet with the precision of trained muscle, Hugh struck out; and Redgrave went down before him —­ thudding upon the door of the veranda like one who falls dead.
