I must state that I have always been deeply interested in the personality of Governor Yoo Shou-chien. Many years ago when I was preparing myself for my second examination, I copied out all the reords I could lay hands on of the criminal cases solved by Governor Yoo when he was still a district magistrate. Poring over those I made it my ambition to learn his brilliant deductive methods. Later I carefully studied his inspired memorials to the Throne and tried to absorb his burning passion for justice and his deep devotion to the state and the people. He was for me the shining example, the ideal of the perfect servant of the state.

How I longed to meet him in person! But that was of course quite impossible since he was a Governor and I but a struggling young candidate.

Then Governor Yoo suddenly resigned. This inexplicable action of my hero perturbed me greatly. I have been wondering about it ever since.

When I found in the archives here in Lan-fang the file Yoo versus Yoo, it seemed to me as if at last I would have an opportunity of coming nearer to the idol of my youth, that I would meet him, as it were, in the spirit. The riddle of his testament seemed to me a challenge from beyond the grave…"

Judge Dee paused and looked intently at the scroll picture hanging on the wall opposite.

As he pointed at it he continued:

"I am firmly resolved to find the secret of that scroll! Since Yoo Kee's confession, the old Governor's message has become more than a challenge. I feel it is my solemn duty to the Governor's memory to see to it that the widow and the son of the man I worshipped obtain what is rightfully theirs. All the more so since I sent his eldest son to the execution ground."

The judge rose and stood himself in front of the picture. His lieutenants left their seats and also gazed once more at the mysterious landscape.

Folding his hands in his sleeves Judge Dee said slowly:

" 'Bowers of Empty Illusion'! How deeply it must have shocked the old Governor when he found that his eldest son had inherited his father's brilliant mind, but nothing of his noble character!

I know every brush stroke of this picture by heart. I had hoped that the old country mansion would have given me some clue, yet I cannot…"

Suddenly the judge stopped. Bending forward he looked over the entire picture from top to bottom. As he straightened himself he slowly tugged at his whiskers. Then he turned round. His eyes were shining.

"I have found it, my friends!" he exclaimed. "Tomorrow, this riddle also will be solved!"

The next day, when Judge Dee opened the morning session of the tribunal hundreds of people were crowding the courtroom. The news of Yoo Kee's arrest had spread all over the town and the wildest rumours were circulating with regard to the arrest of the Uigur chieftain.

Judge Dee slowly surveyed the crowd, and pondered for a while as to how he should start the questioning. He reflected that Yoo Kee excelled in dissimulation and secret planning; he was wont to direct affairs from behind a carefully constructed screen. Often such persons break down completely once they have been forced to come out into the open.

The judge wrote Yoo Kee's name on a slip and handed it to Headman Fang.

As Yoo Kee was brought in Judge Dee saw that his surmise had been correct. Yoo Kee had changed overnight into a different person. The cloak of easy joviality that he had so carefully worn had fallen off. There was left nothing but a listless, broken man.

Judge Dee said quietly:

"At yesterday's session we went through the formalities. You can now begin immediately with your confession!"

"Your Honour", Yoo Kee spoke in a toneless voice, "when a man has been left no hope either in this world or the next there is no reason why he should not tell the whole truth."

Yoo Kee paused for a moment. Then he suddenly said bitterly:

"I know that my father hated me. Well, I hated him too although I admit that I feared him! While he was still alive I had already made the firm resolution that I would become a greater man than he. He had been a governor, I was to be a sovereign ruler!

For years I made a careful study of the border situation. I realized that if the barbarian tribes could be united and given some guidance they could easily overrun the entire border region. With Lan-fang as capital I could found a kingdom astride the border. While keeping off the Chinese authorities by promises of submission and lengthy negotiations about vassalage, I would steadily enlarge the kingdom to the west by attracting more and more barbarian chieftains; thus while my power would be growing in the west, my attitude to the Chinese authorities in the east would gradually stiffen until I would be so strong that no one would dare to attack me."

Yoo Kee heaved a sigh, then went on:

"I was confident that I had sufficient diplomatic skill and knowledge of Chinese internal politics to execute this scheme. But I lacked military experience. In Chien Mow I found a useful tool. He was a determined and ruthless man, but he knew he was not qualified to act as a political leader. I encouraged him to establish himself as the local ruler here and showed him how he could consolidate his position against the central authorities. He acknowledged my leadership. After our plans had materialized, I would have appointed Chien Mow as my Generalissimo. At the same time I used Chien's activities to test the reaction of the central authorities. Everything succeeded, the central government seemed to acquiesce in the irregular situation here. So I resolved to take the next step and establish contact with the Uigur tribes.

Then that interfering fool, Magistrate Pan arrived. Through an unfortunate accident a letter I had written to an Uigur chieftain fell into his hands. I had to act quickly. I ordered Orolakchee, a cousin of the Khan and my confidential agent, to lure Pan to the river and kill him. Chien Mow was angry, he feared that the government would retaliate. But I instructed him how he could cover up this crime, and nothing untoward happened."

Judge Dee was going to interrupt Yoo Kee but on second thoughts he decided that it was better to let him tell his story in his own way. Yoo Kee went on in the same toneless voice:

"I would have come out into the open then were it not that the Khan received information of big Chinese victories over the barbarians in the north. He started to waver and finally withdrew his support. Then I engaged in complicated negotiations with minor chieftains, and finally succeeded in uniting three powerful tribes. They would attack the city if I guaranteed that the Watergate would be open and that the main points inside the town would be occupied by my men.

When the date had been fixed, Your Honour arrived with a regiment of the regular army for inspecting the border, Chien Mow was arrested and his men dispersed. I feared that my plans had leaked out and that in the near future a strong garrison would be sent to Lan-fang. I decided to take immediate action.

Tonight three Uigur tribes will gather in the plain. When at midnight they see the signal fire on the watchtower, they will ford the river and enter the city by the Watergate.

That is all!"

The crowd started to talk excitedly. They realized that they had narrowly escaped being overrun by cruel barbarian horsemen.

"Silence!", shouted Judge Dee.

Then he ordered Yoo Kee:

"State how many men these three tribes can put under arms!

Yoo Kee thought for a while, then he replied:

"About two thousand trained mounted archers, and a few hundred footmen."
