He was not surprised at the direction taken by the carriage in front, which was kept just in sight till it turned into Bow Street, when Chester signed to his driver to stop, and sprang out, turning the corner just in time to see the carriage slowly passing in its turn through the gateway leading under the portico of the opera.

He followed to find that the occupants had alighted, and upon entering the lobby he caught sight of the back of Marion’s dress as she swept through one of the great baize-covered doors.

Here there was a check. The door-keeper held out his hand for the customary ticket, and Chester turned impatiently away, to go to the box-office, when for the first time it struck him that he was not in evening dress, and could not pass into the stalls.

He stood biting his lips, and hesitating as to whether he should take a cab back home, to dress, and return, but he felt that he could not do that. A dozen things might happen to prevent his catching sight of Marion again; and snatching at the first idea that came, he took a ticket for the upper part of the house, hired an opera-glass and then climbed nearly to the top.

Here upon taking a seat he came out again in despair. Even with the aid of the glass he found he could not get a glimpse of a third of the house, and feeling that at all costs he must get into the stalls in as central a position as possible, he descended again to the box-office, and secured a stall nearly in the centre of the third row.

Having made sure of his seat, he hurried back to Raybeck Square calculating that he could be back within an hour.

Bidding the cabman wait, he sprang up to his room, conscious of the fact that Aunt Grace was watching; and after his hurried change he knew by the ajar door of the drawing-room that she was there watching still.

But this passed almost unnoticed in the excitement, and once more he was in the cab, eager and with his imagination running riot.

“What an idiot I was not to ask the number of their box,” he said to himself.

He did ask as soon as he reached the opera house, and found it was almost central on the grand tier; but after taking his place he had no opportunity for turning round till the end of the act in progress, and he sat trembling with excitement and wondering whether Marion had recognised him as he entered.
