his forefinger. When he had found a soft one he put it in his mouth. He ate it and spat the stone on the floor.
'Does Your Honour wish me to eat more?', Woo asked politely.
'This is quite sufficient!', Judge Dee said coldly. 'You may stand back!'
Woo rose and looked around at the constables. They made no move to grab him and lead him back to the jail. So he retreated a few paces and remained standing there. He looked curiously at the judge.
'Let Candidate Ding come forward!', Judge Dee ordered.
As Ding knelt in front of the bench Judge Dee spoke:
'Candidate Ding, I have now discovered who killed your father. This case proved to be a singularly complicated one, I don't pretend to have disentangled all its ramifications. Your father's life was threatened from more than one side, and more than one attempt was made to kill him. This court, however, is concerned only with the one attempt that succeeded. The accused Woo has nothing to do with that. Hence the case against Woo Feng is herewith dismissed!'
A murmur of astonishment rose from the crowd. Candidate Ding remained silent, he did not repeat his accusation of Woo.
Woo cried out:
'Your Honour, has White Orchid been found?'
When the judge shook his head Woo turned round without another word and unceremoniously elbowed his way through the spectators to the door of the court hall.
Judge Dee took a red-lacquered writing brush from the bench.
'Rise, Candidate Ding', he ordered, 'and tell me what you know about this brush!'
As he spoke the judge held out the writing brush to Ding, the open end of the shaft pointing straight at the young man's face.
Candidate Ding looked dumbfounded. He took the brush from Judge Dee's hands and turned it round in his fingers. When he had read the engraved inscription he nodded his head.
'Now I see the inscription I remember, Your Honour! Some years ago when my father was showing me some rare old jade pieces he also took out this writing brush. He told me that it was an advance gift for his sixtieth birthday from a very exalted personage. My father did not reveal his name but he said that that person had told him that since he feared his end was near he wished to present that brush in advance; my father was not to use it until he had actually celebrated his sixtieth birthday.
My father valued this writing brush highly. After he had shown it to me he put it back into the locked box where he kept his jade collection.'
'That writing brush', Judge Dee said gravely, 'is the instrument that killed your father!'
Candidate Ding looked bewildered at the brush in his hands. He scrutinized it carefully and peered inside the hollow shaft. Then he shook his head doubtfully.
Judge Dee had followed intently his every move. Then he said curtly:
'Give that brush back to me. I shall demonstrate how the deed was done!'
When Candidate Ding had handed back the brush, Judge Dee kept it in his left hand. With his right he took a small wooden cylinder from his sleeve and held it up so that every one could see it.
'This', he said, 'is an exact replica in wood of the hilt of the small knife that was found in General Ding's throat; it is just as long as the entire dagger including the blade. I shall now insert it into the hollow shaft of this brush.'
The stick fitted exactly into the shaft. But when it had gone in for half an inch, it stuck.
Judge Dee handed the brush to Ma Joong.
'Press this stick further down!', he ordered.
Ma Joong placed his large thumb over the protruding end of the stick. With evident difficulty he pressed it down till it had disappeared into the shaft.
He looked expectantly at the judge.
'Stretch out your arm and release your thumb as quickly as you can!' ordered, the judge.
The wooden stick shot up in the air for about five feet, then clattered down on the stoneflags.
Judge Dee leaned back in his chair. Stroking his beard he said slowly:
'This writing brush is an ingenious instrument of death. Its hollow shaft contains a number of thin coils of what I presume to be southern rattan. After he had inserted these coils the person who made this instrument pressed them down as far as they would go with a hollow tube. He poured melted resin of the lacquer tree down that tube and held the coils down till the resin had completely dried. Then he removed the tube and replaced it by this.'
Judge Dee opened a small box and with great care took from it the knife that had been found in the dead General's throat.
'You will see', he continued, 'that its tubular hilt fits exactly into the shaft of this brush, while its hollow blade fits its curved inside. Even if one peered into the shaft, the knife would be invisible.
Some years ago a certain person presented this writing brush to the General and therewith pronounced his death sentence. He knew that when the General would use this brush, he would sooner or later burn its tip in a candle to discard the superfluous hairs, as we all do when we start writing with a new brush. The heat of the flame would soften the resin, the coils would be released and the poisoned knife would shoot out of the shaft. It was a ten to one chance that it would hit the victim in the face or throat. Afterwards the coils would be invisible because they would have stretched out along the inside to the hollow shaft.'
While Judge Dee was speaking Candidate Ding had first shown an expression of utter bewilderment. Slowly this expression had changed to one of incredulous horror. Now he cried out:
'Who, Your Honour, contrived this diabolical device?'
'He signed his name to the deed', Judge Dee said quietly. 'But for that fact I would never have solved this riddle. Let me read out to you the inscription:
'With respectful congratulations on the completion of six cycles. The Abode of Tranquillity.' '
'Who is that? I have never heard that studio name!', Candidate Ding cried out.
Judge Dee nodded.
'It was known only to a few intimate friends', he replied. Yesterday I found out that it is the pen name of the late Governor Yoo Shou-chien!'
Loud exclamations rose from the audience.
When the excitement had subsided Judge Dee spoke:
'It so happens that on the same day both the father and the son appear in this tribunal, the son alive and the father in spirit.
You, Candidate Ding, will probably know better than I what deed of your father motivated old Governor Yoo to condemn him to death and to execute the sentence himself in this singular way. However this may be, I cannot proceed against the dead. I, the magistrate, herewith declare the case closed!'
Judge Dee let his gavel descend on the bench. He rose and disappeared through the screen behind the dais.
While the spectators filed out of the court hall they talked excitedly about the unexpected solution of the General's murder. They were full of praise for Judge Dee for having found out this ingenious device. A few elderly men with experience in court matters, however, were doubtful. They could not understand the significance of the incident of the box with plums and remarked to each other that evidently there was more to this case than met the eye.
When Headman Fang entered the quarters of the guards he found Woo waiting for him.
Woo bowed deeply for the headman and said hastily:
'Please allow me to take part in the search for your daughter!'
Headman Fang looked at him thoughtfully. Then he answered:
'Since you, Mr. Woo, were prepared to suffer severe torture for my daughter's sake, I shall welcome your assistance. I have an order to carry out just now. Wait here for a few moments, when I am back I shall tell you everything about our first unsuccessful search.'
Cutting short Woo's protests, the headman walked to the gate and surveyed the crowd that was streaming out. He saw Candidate Ding who was just stepping out into the street. Headman Fang overtook him and said:
'Mr. Ding, His Excellency would like to see you for a moment in his private office.'
Judge Dee was sitting behind his desk with his four lieutenants gathered round him. The judge had ordered
