So after Max had been round to his rooms to put on a suit of dark tweeds, he went to Charlie’s chambers where the various implements were produced and laid upon the table. It was then nearly ten o’clock.

Rolfe, having sent Green to the other end of Jermyn Street out of the way, drew out the whisky decanter from the tantalus stand, poured out two “pegs” with soda, and drank:

“Success to the elucidation of old Statham’s secret.”

Then, carefully stowing the various articles in their pockets, they slipped down into the street and were out of sight before the inquisitive Green had returned.

Arrived in Park Lane, after a hasty walk, they strolled slowly along by the park railings past the house. All was in darkness save the hall, where the electric lamp showed above the fanlight. Old Sam was probably in his study, smoking his last cigar, for the shutters were that night closed, as they sometimes were. The shutters of the basement were also closed behind their iron bars, while at the upstairs windows all the blinds were carefully drawn.

Indeed, the exterior of the house presented nothing unusual. It was the same as any other mansion in Park Lane. Yet there were many who on going up and down the thoroughfare afoot or on the motor-’buses jerked their thumbs at it and whispered. The house had earned a reputation for mystery. Sam Statham was a mystery in himself, and of his house many weird things were alleged.

Thrice the pair passed and repassed. At the corner of Deanery Street stood a constable, and while he remained there it was injudicious to attempt an entry with a latchkey. So they strolled back in the direction of the fountain, conversing in undertones.

Max glanced at his watch, and found that it wanted a quarter to eleven. At last they crossed the road and passed the door. All seemed quiet. At that moment the only object in sight was a receding motor-’bus showing its red tail-light. Not a soul was on the pavement.

“All clear!” cried Charlie, scarce above a whisper, as he slipped up the two or three steps, followed by his companion.

That moment was an exciting one. Next second, however, the key was in the latch, and without a sound the wards of the lock were lifted.
