“Thank you,” she answered, breathing more freely. The knowledge that he had escaped to Brussels, and that she could give him further warning, if needed, was to her reassuring. “It is extremely kind of you to bring me this welcome message. I had no idea that you knew Mr Armytage.”

“We were at Eton together,” Gregory answered. “I’ve known him ever since I can remember. But I see my brother is going to drive the Blatherwycke parson home, so I must say good-bye; and I hope to call again, as soon as I have any further news—if I may.”

She answered him with a glance. Then together they returned into the centre of the room, chatting as if no confidences had been exchanged, and a moment later he took leave of her.

Next morning, in a dark stuff walking dress, she mounted her cycle, having announced her intention to ride over to King’s Cliffe and lunch with some friends of Malvano’s who had invited her. Instead, however, she went to Gretton Station, placed her cycle in the cloakroom, and took a first-class ticket to London, determined to keep the mysterious appointment. It was nearly three o’clock when she arrived, and she at once lunched at the railway buffet, idled there for half an hour, and then took a cab to Regent Street, where she whiled away the time gazing into the windows of the milliners and dressmakers, unaware that a shabby, middle-aged, unimportant-looking man was narrowly watching her movements, or that this man was Inspector Elmes of Vine Street.

At last she glanced at her little watch, with its two hearts set in diamonds on the back—a beautiful souvenir which her absent lover had given her in the early days of their acquaintance—and found it wanted ten minutes to five. She had passed the obscure rendezvous, and glanced at its window with the sickly looking palms and india-rubber plants, the long-necked wine-flasks she knew so well, and the two framed menus; therefore, considering it time to enter the place, she retraced her steps from Piccadilly Circus, and a few minutes later opened the door and walked into the long, narrow salon, with its marble-topped tables and plush lounges.

Two or three men, whom she at once recognised as compatriots, were sipping coffee and smoking. As she passed, they eyed her admiringly; but without a glance at them she walked to the further end, and seating herself at a table on the left, ordered coffee.

Scarcely had it been brought, when the door again opened, and there lounged in leisurely a tall, well-built, handsome man in long dark overcoat and brown soft felt hat. Without hesitation he walked straight to her table, bowed politely, and with a word of greeting seated himself. Her face went white as the marble before her; she held her breath. In that instant she recollected it was the day, the hour, and the place mentioned in that remarkable letter found upon her unfortunate friend Vittorina—that letter which had so puzzled and mystified the Ambassador, the police, the newspaper reporters, and the British public.

She had been entrapped.
