As the Governor issued from the house and was about to enter his carriage, which waited before the door, he caught sight of the Superintendent of Police, who was coming up the street, and who quickened his steps on perceiving him.

"I was just going up to see your Excellency," said he, bowing respectfully. "I thought I should find you at the Castle."

"I am now returning thither," replied Raven, pointing to the carriage. "May I ask you to accompany me?"

The Superintendent accepted the invitation, and both gentlemen entered the carriage, which started at once on its way to the Castle. The Baron listened in silence to the other's talk. He was moody and abstracted, chafing inwardly at the first humiliation openly laid upon him. So far they had left him free scope, had invested him with an unlimited authority such as no Governor before him had possessed; and now, at the present juncture, when he was more than ever in want of this authority, he suddenly found himself checked, his course of action impeded, his hands bound. They were taking from him the support whereon he had relied, the powerful ally whom he had once called to his aid, and on whom now he was forced in some measure to depend. They were purposely leaving him alone to face the struggle with the rebellious city. Raven was not at a loss to interpret this symptom.

The Superintendent had been speaking of some unimportant incidents which had occurred the preceding day. Now he went on to say: "But I have a communication to make which will surprise your Excellency. You take an interest in young Dr. Brunnow?"

Raven grew attentive.

"Certainly. What of him?"

"Nothing personally, though I am sorry to say the matter in question touches him very nearly. You remember the gentleman who was introduced to us the other evening by Councillor Moser as Dr. Franz? You had even, I think, some lengthened conversation with him afterwards. Did nothing in his manner strike you as peculiar?"

The Baron drew himself up quickly. The allusion sufficed to show him that his suspicion had been well-founded, and that danger to Brunnow was impending. It was imperatively necessary to show a calm front, in order, if it were yet possible, to avert a catastrophe. Raven summoned up all his self-possession, and answered with a cold, imperturbable "No."

"Well, my attention was attracted to him at once," said the Superintendent. "Even during those few short minutes doubts occurred to me, doubts which were subsequently strengthened by some remarks the Councillor inadvertently let fall. So I thought it advisable to set some inquiries on foot. Now that there are so few strangers in the town, it was no difficult matter to find out where the pretended Dr. Franz had put up. He had arrived a couple of hours before at an inn in the suburbs, had displayed great solicitude in speaking of the young doctor, asking many questions about him in an agitated manner, and had then hurried off to see him. The trunk, which had been imprudently left at the inn, bore the ticket Z---- as the station of departure. There were other very suspicious circumstances in support of the evidence--in short, no doubt now exists that we have to do with Rudolph Brunnow, the father of the wounded man."
