the front door. The Killer goes back outside. The young woman disappears into the back of the bank. The Killer opens the front door. The young woman has a pair of slippers waiting for him. The Killer takes off his boots in the genkan. The young woman tells him that the manager has already left, but that the assistant manager will see him. The Killer nods and thanks the young woman. The young woman leads the Killer through the bank. The Killer passes the rows of clerks at their desks. The young woman introduces the Killer to the assistant manager. The Killer bows. The assistant manager offers the Killer a seat. The Killer sits down, his face to the right. The assistant manager stares at the name-card. The Killer tells the assistant manager there has been an outbreak of dysentery in the neighbourhood. The assistant manager now presents his own name-card. The Killer tells Mr Yoshida that the source of the outbreak is the public well in front of the Aida residence in Nagasaki 2-chōme. Mr Yoshida nods and mentions that the bank’s manager, Mr Ushiyama, has in fact left early due to severe stomach ache. The Killer tells Mr Yoshida that one of Mr Aida’s tenants has been diagnosed with dysentery and that this man made a deposit in this branch today. Mr Yoshida is amazed that the Ministry of Health and Welfare has heard of the case so quickly. The Killer tells Mr Yoshida that the doctor who saw Mr Aida’s tenant reported the case promptly. Mr Yoshida nods. The Killer says he has been sent by Lieutenant Parker, who is in charge of the disinfecting team for this area. Mr Yoshida nods again. The Killer has been told to inoculate everyone against dysentery and to disinfect all items that may have become contaminated. Mr Yoshida nods for a third time. All members, all rooms, all cash and all money in this branch, says the Killer. Mr Yoshida stares at the name-card again. The Killer says that no one will be allowed to leave until his work has been completed. Mr Yoshida glances at his watch. Lieutenant Parker and his team will arrive soon to check the job has been done properly, says the Killer. Mr Yoshida nods. The Killer now places his small olive-green bag on Mr Yoshida’s desk. Mr Yoshida watches the Killer open the bag. The Killer takes out a small metal box and two different-sized bottles marked in English. Mr Yoshida reads the words FIRST DRUG on the smaller 200CC bottle and SECOND DRUG on the 500CC bottle. The Killer tells Mr Yoshida that this is an extremely potent oral antidote which the Americans have recently developed through experiments with palm tree oil. Mr Yoshida nods. It is so powerful that you will be completely immunized from dysentery, says the Killer. Mr Yoshida nods again. The Killer warns Mr Yoshida that the administration procedure is complicated and unusual. Again, Mr Yoshida glances at the name-card on his desk. The Killer asks Mr Yoshida to gather his staff. Even the caretaker, his wife and two children? asks Mr Yoshida. The Killer nods. Mr Yoshida rises from his desk. The Killer turns to the young woman and asks her to bring enough teacups for all the members of the branch. The young woman fetches sixteen teacups on a tray. The Killer opens the smaller bottle marked FIRST DRUG. Each member of the branch, including the caretaker, his wife and two children, gathers around Mr Yoshida’s table. The Killer asks if everybody is here. The assistant manager counts heads and nods. The Killer holds a pipette in his hand. Each member watches as the Killer drips some clear liquid into each of their cups. The Killer asks each member to pick up their teacup. Each member reaches for their own cup. Now the Killer raises his hand in warning. Each member listens as the Killer tells them of the strength of the serum, the damage it can cause to their gums and tooth enamel if they do not watch his demonstration carefully and follow his instructions precisely. The Killer now takes out a syringe. Each member watches as the Killer dips his syringe into the liquid. The Killer draws up a measure of the liquid into the syringe. Each member sees the Killer open his mouth. The Killer places his tongue over his bottom front teeth and tucks it under his lower lip. Each member watches as
