From the direction of the desk came the soft scratching of pen on paper. Ferris was plainly making quite a job of it, putting all his energies into his task. He seemed to be one of those writers, like Flaubert, who spared no pains in the quest for perfect clarity and are prepared to correct and re-correct indefinitely till their artist-souls are satisfied. It seemed to Mrs. Waddington as though her vigil was to go on for ever.

But in a bustling city like New York it is rarely that the artist is permitted to concentrate for long without interruption. A telephone-bell broke raspingly upon the stillness: and the first sensation of pleasure which Mrs. Waddington had experienced for a very long time came to her as she realised that the instrument was ringing in the passage outside and not in the room. With something of the wild joy which reprieved prisoners feel at the announcement of release she heard the butler rise. And presently there came from a distance his measured voice informing some unseen inquirer that Mr. Biffen was not at home.

Mrs. Waddington rose from her form. She had about twenty seconds in which to act, and she wasted none of them. By the time Ferris had returned and was once more engrossed in his literary composition, she was in the kitchen.

She stood by the window, looking out at the fire-escape. Surely by this time, she felt, it would be safe to climb once more up to the roof. She decided to count three hundred very slowly and risk it.

CHAPTER FIFTEEN

Molly and Sigsbee Horatio, the latter muttering "Gallagher! Gallagher! Gallagher!" to himself in order that the magic name should not again escape him, had started out in the two-seater about a quarter of an hour after the departure of Mrs. Waddington's Hispano-Suiza. Half-way to New York, however, a blow-out had arrested their progress: and the inability of Sigsbee H. to make a quick job of fixing the spare wheel had further delayed them. It was not, therefore, till almost at the exact moment when Mrs. Waddington was committing the rash act which had so discomposed Officer Garroway, that Molly, having dropped her father at Police Headquarters, arrived at the entrance of the Sheridan.

She hurried up the stairs and rang George's front-door bell. For awhile it seemed as if her ringing was to meet with no response: then, after some minutes, footsteps made themselves heard coming along the passage. The door opened, and Molly found herself gazing into the inflamed eyes of a policeman.

She looked at him with surprise. She had never seen him before, and she rather felt that she would have preferred not to see him now: for he was far from being a pleasing sight. His nose, ears and eyes were a vivid red: and his straggling hair dripped wetly on to the floor. With the object of diminishing the agony caused by the pepper, Officer Garroway had for some time been holding his head under the tap in the kitchen: and he now looked exactly like the body which had been found after several days in the river. The one small point that differentiated him from a corpse was the fact that he was sneezing.

"What are you doing here?" exclaimed Molly.

"Achoo!" replied Officer Garroway.
