"It will, indeed," murmured Brett; "and no doubt the somebody in question will experience a certain amount of inconvenience before he proves to you that he had nothing whatever to do with the matter. Now, don't answer me, Winter, but ponder seriously over this question: Do you really think that the intelligence which planned and successfully carried through an operation of such magnitude will be trapped by plain-clothes constables watching the gangways of steamships, or by any pawnbroker who has ever lent half the value of a pledge?" Almost impatiently the barrister waved the subject out of the hansom, and the detective had sense enough to leave him alone during the few remaining minutes before the vehicle pulled up near the Albert Gate mansion. Brett stopped the driver some little distance short of the house itself, as he did not wish to attract the attention of a knot of curious sightseers in the street. He asked Winter to precede him and make known the fact that he was coming, so that there would be no delay at the door. This the detective readily agreed to, and Brett rapidly took in the main external features of the house which had become the scene of such a remarkable tragedy. It was a palatial structure, built on the sombre lines of the Early Victorian period. Miss Talbot's brief description of the measures taken to protect its occupants from interference was fully borne out by its aspect. There was no access to the basement; the main entrance was situated at the side; all the ground-floor and first-storey windows facing into the street were fitted with immovable wooden venetians. Presumably those on the Park side were similarly secured, whilst the back wall abutted on to that of another mansion, equally large and strongly built, tenanted by a well-known peer. Truly, it required a genius almost unrivalled in the annals of crime to murder four people and steal diamonds worth millions in such a place whilst guarded by twelve London policemen and under the special protection of the Home Office. The appearance of Winter at the door caused the gaping idlers in the street to endeavour to draw nearer to the mysterious portals. Thereupon three policemen on duty outside hustled the mob back, and Brett took advantage of the confusion thus created to slip to the doorway almost unperceived. One of the police constables turned round to make a grab at him, but a signal from a _confrère_ inside prevented this, and Brett quickly found himself within a spacious entrance hall with the door closed and bolted behind him. Winter was talking to two uniformed inspectors, to whom he had explained the barrister's mission and credentials. "We have here, Mr. Brett," he said, "Inspector Walters, who was on duty until ten o'clock on Monday night, and Inspector Sharpe, who relieved him. They will both tell you exactly what took place."
