'Just ten days ago, on the seventeenth day of this month, a butcher called Hsiao Foo-han, who owns a small shop in Half Moon Street in the south-west corner of the city, came rushing in tears to the noon session of this tribunal. He was accompanied by three witnesses, namely Gao the warden of the southern quarter, Loong a tailor who lives opposite Hsiao's shop, and the master of the Butchers' Guild.

'Butcher Hsiao presented a written accusation against Wang Hsien-djoong, a Candidate of Literature; this Wang is a poor student who also lives near the butcher's shop. Hsiao claimed that Wang had strangled his only daughter Pure Jade in her bedroom and made off with a pair of golden hairpins. Butcher Hsiao mentioned that Candidate Wang had been having an illicit love affair with his daughter for six months already. The murder was not discovered until she failed to appear that morning for her usual household duties.'

'That Butcher Hsiao,' Judge Dee interrupted, 'must be either a complete fool or a greedy rogue! How could he permit his young daughter to conduct a love affair under his own roof, degrading his house to a brothel? No wonder that violence and murder took place there!'

Sergeant Hoong shook his head.

'No, Your Honour,' he said, 'Butcher Hsiao's explanation placed the crime in quite another light!'

Judge Dee folded his hands in his wide sleeves.

'Proceed!' he said briskly.

'Until that very morning,' Sergeant Hoong continued, 'Butcher Hsiao had been completely ignorant of the fact that Pure Jade had a lover. She slept in a garret that served as laundry and sewing-room, and built over the godown that stands somewhat apart from the shop. They have no servants, all the housework there is done by the wife and the daughter. Experiments made on the orders of Judge Feng showed that even a loud voice in the girl's garret could not be heard either in the butcher's bedroom, or by the neighbours.

'As to Candidate Wang, he is a member of a well-known clan in the capital. But both his parents are dead and owing to a family quarrel he is penniless. While preparing for the second degree literary examination he has been eking out a meagre living by teaching the children of the shopkeepers in Half Moon Street. He rents a small attic over the shop of Loong, an aged tailor, directly opposite Butcher Hsiao.'

'When did the love affair start?' Judge Dee asked.

'About half a year ago,' Sergeant Hoong answered, 'Candidate Wang fell in love with Pure Jade and the two arranged secret meetings in the girl's room. Wang would go there towards midnight, slip in through the window, and steal back to his own quarters before dawn. Tailor Loong testified that he had discovered Wang's secret after a few weeks and severely reprimanded him, adding that he would inform Butcher Hsiao about the disgraceful affair.'

The judge nodded. He said approvingly:

'That tailor was perfectly right!'

The Sergeant consulted a document roll before him. Then he said:

'Wang evidently is a cunning rascal. He fell on his knees and assured Tailor Loong that Pure Jade and he were deeply in love with each other. He swore to marry her as soon as he had passed his second degree. He would then be in a position to offer Butcher Hsiao a suitable wedding gift and to give his bride a proper home. Wang added that if his secret became known he would be barred from the literary examinations and that the affair would then end in disgrace for all concerned.

'Tailor Loong knew that Wang was a studious youngster who would certainly pass the examinations this autumn. Moreover he was secretly very proud that a scion of a noble family who would soon be an official had chosen the daughter of his neighbour as his bride-to-be. Finally he promised that he would not betray the secret, appeasing his own conscience by the consideration that after a few weeks the affair would be honourably concluded by Wang asking Pure Jade in marriage. However, in order to convince himself that Pure Jade was not a girl of loose morals, Tailor Loong from then on kept an eye on the butcher's shop; he testifies that Wang was the only man Pure Jade knew, and the only man who ever came near her room.' Judge Dee sipped his tea. Then he said sourly:

'Be that as it may! Yet the fact remains that the conduct of these three people-Pure Jade, Candidate Wang and Tailor Loong is most reprehensible!'

'That point,' Sergeant Hoong observed, 'was duly brought out by Judge Feng's sharp denunciation of Tailor Loong for his connivance, and of Butcher Hsiao for his laxity in supervising his household. 'Now, when on the morning of the seventeenth Tailor Loong learned about Pure Jade's murder, his affection for Wang changed into violent hatred. He rushed to Butcher Hsiao and told him all about Pure Jade's affair with Wang. I quote his actual words: "I, miserable wretch, condoned this sordid affair while all the time that dogshead Wang was using Pure Jade for his base lust. When she insisted that he marry her, he killed her and stole her golden hairpins in order to buy himself a wealthy wife!"

'Butcher Hsiao, distraught by rage and grief had Warden Gao and the master of his guild called. They held counsel together and all agreed that Wang was the murderer. The guildmaster drew up the written accusation and then they all went to the tribunal to charge Wang with this foul crime.'

'Where was Candidate Wang at that time?' Judge Dee asked. 'Had he fled from the city?'

'No,' the sergeant answered, 'he was caught immediately. When Judge Feng had completed hearing Butcher Hsiao, he sent out his constables to arrest Wang. They found him in his attic over the tailor's shop, fast asleep although it was well past noon. The constables dragged him to the tribunal. There Judge Feng confronted him with Butcher Hsiao's accusation.' Judge Dee straightened himself. Leaning forward he placed his elbows on the desk and said eagerly:

'Now I am very interested to hear how Candidate Wang formulated his defence!'

Sergeant Hoong selected a few papers. After glancing them through he said:

'That rascal had an explanation for everything. His main point was ----'

Judge Dee raised his hand.

'I prefer,' he said, 'to have it in Wang's own words. Read me the transcript!'

Sergeant Hoong looked astonished. He seemed about to make a remark but thought better of it. Hunched over the papers before him he began to read out in a monotonous voice the verbatim court record of Candidate Wang's statement.

'This ignorant student kneeling before Your Honour's dais is overcome with shame and mortification. He pleads guilty of the most reprehensible offence of having conducted a love affair with a maiden of unblemished reputation. It so happens that the attic where I sit every day reading the Classics faces the room of Pure Jade. It is on the corner of the blind alley on the other side of Half Moon Street. I often watched her as she was combing her hair in front of her window, and I resolved that she alone should be my future bride.

'It would have indeed been fortunate if I had confined myself to that resolution and waited till after my examination before taking any steps. Then I would have been in a position to approach a go-between with an appropriate wedding gift and thus have Pure Jade's father acquainted with my intentions in the customary and honourable way. One day, however, I chanced to meet Pure Jade alone in the alley. I could not refrain from engaging her in conversation. When she gave me to understand that my feelings were reciprocated I, who should have guided this innocent girl, fanned her own passion by my own: I arranged further meetings in the alley. Soon I persuaded her to allow me to visit her secretly in her room just once. Late on the appointed night I placed a ladder under her window and she let me in. Thus I enjoyed the pleasure which, if indulged in with an honourable maid, is forbidden by the Command of Heaven unless previously solemnified by the ceremony of marriage. 'And, just as a fire will burn higher when more fuel is added, my guilty passion exacted more frequent meetings. Since I feared that the ladder might be noticed by the night-, watch or a late passer-by, I persuaded Pure Jade to let a long
