My Lord Marquis swiveled his head and glared at Lord Bontriomphe. “Are you an accessory to this imbecilic tomfoolery?”

Lord Bontriomphe shook his head once, left to right. “No, my lord. But it does look as though he has us dead to rights, doesn’t it?”

“Buffoon!” the Marquis snorted. He looked back at Lord Darcy. “Very well. I know when I am being gulled as well as you do. I regret having jailed Master Sean; it was frivolous. And you are well aware that I would just as soon go to the Tower myself as to lose the services of Lord Bontriomphe for any extended length of time. Outside this building, he is my eyes and ears. I will sign an order for Master Sean’s release immediately. Since you have been assigned to this case by the King, you will, of course, be remunerated from the Royal Privy Purse?”

“Beginning today, yes,” said Lord Darcy. “But there is the little matter of yesterday — including cross-Channel transportation, train ticket, and cab fare.”

“Done,” the Marquis growled. He signed a release form, poured melted sealing wax on it, and stamped it with the seal of the Marquisate of London, all without a word. Then he heaved his massive bulk out of the chair. “Lord Bontriomphe, give my lord cousin what is owed him. Open the wall safe and take it out of petty cash. I am going upstairs to the plant rooms.” He did not quite slam the door as he left.

Lord Bontriomphe looked at Lord Darcy. “Look here — you don’t really think…”

“Chah! Don’t be ridiculous. I know perfectly well that every word of your narrative was accurate and truthful. And the Marquis is quite aware that I know it.” Lord Darcy was not one to err in a matter of judgment like that, and, as it turned out, he did not. Lord Bontriomphe’s recital was correct and precise in every detail.

“Let’s get to the Tower,” said Lord Darcy.

Lord Bontriomphe was at his desk taking a pistol out of a drawer. “Just a second, my lord,” he said, “I once resolved never to go out on a murder case unarmed. By the way, don’t you think it would be best to set up an auxiliary headquarters in the Royal Steward? That way we can keep in touch with each other and with Chief Hennely’s plainclothes investigators.”

“An excellent idea,” said Lord Darcy, “and speaking of plainclothes investigators, did you get statements from everyone concerned yesterday?”

“As many as possible, my lord. Of course, we couldn’t get everyone, but I think the reports we have now are fairly complete.”

“Good. Bring them along, will you? I should like to look them over on our way to the Tower. Are you ready to go?”

“Ready, my lord,” said Lord Bontriomphe.

“Very well, then,” said Lord Darcy. “Come, let’s get Master Sean out of durance vile.”

As the official carriage, bearing the London arms, moved through the streets toward the Royal Steward Hotel, its pneumatic tires jouncing briskly on their spring suspensions as a soft accompaniment to the clopping of the horses’ hooves, Sean O Lochlainn, Master Sorcerer, leaned back in the seat, clutching his symbol-decorated carpetbag to his round paunch.

“Ah, my lords,” he said to the two men on the seat opposite, “a relief it is, indeed, to be free again. Twenty-four hours of sitting in the Tower is not my notion of a grand time, and you may be sure of that. Not that I object to being alone in a comfortable room for a while; any sorcerer who doesn’t take a week or so off every year for a Contemplation Retreat will find his power deserting him. But when there’s work to be done…” He paused. “My lord, you didn’t get me out of the Tower by solving this case, did you?”

Lord Darcy laughed. “No fear, my good Sean. You haven’t missed any of the excitement yet.”

“His lordship,” said Lord Bontriomphe, “got you out by simple but effective blackmail.”

“Counter-blackmail, if you please,” Lord Darcy corrected. “I merely showed de London that Lord Bontriomphe could be jailed on the same sort of flimsy evidence that the Marquis used to jail you.”

“Now wait a moment,” said Lord Bontriomphe. “The evidence wasn’t all that flimsy. There was certainly enough — in both cases — to permit holding a man for questioning.”

“Certainly,” Lord Darcy agreed. “But My Lord Marquis had no intention of questioning Master Sean. He was adhering to the letter of the law rather than to its spirit. It is a matter of family rivalry; we have, the Marquis and I, similar although not identical abilities, and therefore a basically friendly but at times emotionally charged antagonism. He would not dare have locked up an ordinary subject of His Majesty on such evidence unless he honestly believed that the suspect had actually committed the crime. Indeed, I will go further: he would never even have considered such an act.”

“I’m glad to hear you say that,” said Lord Bontriomphe, “since it happens to be true. But once in a while, this rivalry goes a little too far. Normally, I keep out of it, but then—”

“Permit me to correct you,” Lord Darcy said with a smile. “Normally, you do not keep out of it. To the contrary, you are normally rigidly loyal to My Lord Marquis; you normally take his side, forcing me to outwit both of you — an admittedly difficult job. This time, however, you felt that imprisoning Master Sean in order to get at me was just a little too much. I am well aware that, had it been I who went to the Tower, the matter would have been quite different.”

Lord Bontriomphe gazed dreamily at the roof of the carriage. “Now there’s a thought,” he said in a speculative tone.

“Don’t think on it too hard, my lord,” said Master Sean with gentle menace. “Not too hard at all, at all.”

Lord Bontriomphe brought his eyes down sharply and started to say something, but his words were forever lost as the carriage slowed suddenly and the driver opened the trapdoor in the roof and said:

“The Royal Steward, my lords.”

Half a minute later, the footman opened the door, and the three men got out. Lord Bontriomphe quietly slipped a couple of large coins into the footman’s hand. “Wait for us, Barney. See that the carriage and horses are taken care of, and then you and Denys wait in the pub across the street. We may be quite some time, so have a few beers and relax. I’ll send word if we need you.”

“Very good, my lord,” Goodman Barney said warmly. “Thank you.”

Then Lord Bontriomphe followed Lord Darcy and Master Sean into the Royal Steward.

Lord Darcy was standing alone just inside the foyer, looking through the glass-paned doors at the crowd in the lobby.

“Where’s Master Sean?” Bontriomphe asked.

“In there. I sent him on ahead. As you will observe, there are at least a dozen well-wishers and possibly two dozen who are merely curious, all of whom are crowded around Sean, congratulating him upon his release, saying they knew all along he was innocent, and pumping him for information about the murder of Sir James Zwinge. While their attention is thus distracted, my lord, you and I will make a quiet entrance and go directly to the murder room. Come.”

They did not attract attention as they went in. This was Visitors’ Day at the Sorcerers Convention, and the lobby was filled with folk who had come to see the displays and the sorcerers themselves. They were just two more sightseers.

At one of the display booths, a journeyman sorcerer was demonstrating a children’s toy to two wide-eyed children and a fondly patronizing father. It consisted of a six-inch black wand with one white tip, five differently-colored pith balls an inch in diameter, and a foot-long board with six holes in it, five of which were ringed with colors to match the balls and the fifth one ringed with white.
