"But that doesn't bring us any nearer to finding out what is Boris Waberski's strong suit, does it? We haven't a clue to it," he said ruefully.

To both of the men, indeed, Mr. Haslitt's flat, unillumined narrative of facts, without a glimpse into the characters of any of the participants in the little drama, seemed the most unhelpful thing. Yet the whole truth was written there—the truth not only of Waberski's move, but of all the strange terrors and mysteries into which the younger of the two men was now to be plunged. Jim Frobisher was to recognise that, when, shaken to the soul, he resumed his work in the office. For it was interrupted now.

Mr. Haslitt, looking out of the window over his partner's head, saw a telegraph-boy come swinging across the square and hesitate in the roadway below.

"I expect that's a telegram for us," he said, with the hopeful anticipation people in trouble have that something from outside will happen and set them right.

Jim turned round quickly. The boy was still upon the pavement examining the numbers of the houses.

"We ought to have a brass plate upon the door," said Jim with a touch of impatience; and Mr. Haslitt's eyebrows rose half the height of his forehead towards his thick white hair. He was really distressed by the Waberski incident, but this suggestion, and from a partner in the firm, shocked him like a sacrilege.

"My dear boy, what are you thinking of?" he expostulated. "I hope I am not one of those obstinate old fogies who refuse to march with the times. We have had, as you know, a telephone instrument recently installed in the junior clerks' office. I believe that I myself proposed it. But a brass plate upon the door! My dear Jim! Let us leave that to Harley Street and Southampton Row! But I see that telegram is for us."

The tiny Mercury with the shako and red cord to his uniform made up his mind and disappeared into the hall below. The telegram was brought upstairs and Mr. Haslitt tore it open. He stared at it blankly for a few seconds, then without a word, but with a very anxious look in his eyes, he handed it to Jim Frobisher.
