He had seen all those things too often ever to forget them— had been deceived, maddened, dared, defied, and outwitted by them in too many adventures to believe that their owner would ever be guilty of an empty hoax. And the thought that the Saint was roving at large that night was not comforting. The air above Middlesex had literally swallowed him up, and he might have been anywhere between Berlin and that very room.
When the dawn came Teal was still awake. The private detective's handlebars ceased vibrating with a final snort; the officer on the couch woke up, and the one who had kept the night watch took his place. Teal himself was far too wrought up to think of seizing his own chance to rest. Ten o'clock arrived before the Prince's breakfast, and Schamyl came through from his bedroom as the waiter was laying the table.
He peered into the box where the crown was packed, and stroked his beard with an ironical glint in his eyes.
'This is very strange, Inspector,' he remarked. 'The crown has not been stolen! Can it be that your criminal has broken his promise?'
With some effort, Teal kept his retort to himself. While the Prince attacked his eggs with a healthy appetite, Teal sipped a cup of coffee and munched on a slice of toast. For the hundredth time he surveyed the potentialities of the apartment. The bedroom and the sitting-room opened on either side of a tiny private hall, with the bathroom in between. The hall had a door into the corridor, outside which another detective was posted; there was no other entrance or exit except the open windows overlooking Hyde Park, through which the morning sun was streaming. The possibility of secret panels or passages was absurd. The furniture was modernistically plain, expensive, and comfortable. There was a chesterfield, three armchairs, a couple of smaller chairs, a writing desk, the centre table on which breakfast was laid, and a small side table on which stood the box containing the crown of Cherkessia. Not even a very small thief could have secreted himself in or behind any of the articles. Nor could he plausibly slip through the guards outside. Therefore, if he was to make good his boast, it seemed as if he must be inside already; and Teal's eyes turned again to the moustached representative of the Southshire Insurance Company. He would have given much for a legitimate excuse to seize the handlebars of that battle-scarred sleuth, one in each hand, and haul heftily on them; and he was malevolently deliberating whether such a manoeuvre could be justified in the emergency when the interruption came.
It was provided by Peter Quentin, who stood at another window of the hotel vertically above the Prince's suite, dangling a curious egg-shaped object at the end of a length of cotton. When it hung just an inch above Schamyl's window, he took up a yard of slack and swung the egg-shaped object cautiously outwards. As it started to swing back, he dropped the slack, and the egg plunged through the Prince's open window and broke the cotton in the jerk that ended its trajectory.
Chief Inspector Teal did not know this. He only heard the crash behind him, and swung around to see a pool of milky fluid spreading around a scattering of broken glass on the floor. Without stopping to think he made a dive towards it, and a gush of dense black smoke burst from the milky pool like a flame and struck him full in the face.
He choked and gasped, and groped around in a moment of utter blindness. In another instant the whole room was filled with a jet-black fog. The shouts and stumblings of the other men in the room came to him as if through a film of cotton-wool as he lumbered sightlessly towards the table where the crown had stood. He cannoned into it and ran over its surface with frantic hands. The box was not standing there any longer. In a sudden panic of fear he dropped to his knees and began to feel all over the floor around the table. . . .
He had already made sure that the box had not been knocked over on to the floor in the confusion, when the smoke in his lungs forced him to stagger coughing and retching to the door. The corridor outside was black with the same smoke, and in the distance he could hear the tinkling of fire alarms. A man collided with him in the blackness, and Teal grabbed him in a vicious grip.
'Tell me your name,' he snarled.
'Mason, sir,' came the reply; and Teal recognised the voice of the detective he had posted in the corridor.
His chest heaved painfully.
'What happened?'
'I
