Black Briefcase Containing Cash

The Black Briefcase Containing Cash is a black suitcase hidden inside a panel behind a train-car trash bin. Its contents make it valuable, but its movement through the train gives it a second role: it is an object that different people can conceal, recover, inspect, and reposition while others search for it. The Prince’s recovery of the case with Kimura exposes both what it contains and how little its cash alone interests him; after taking its five debit cards, he intends to return the locked suitcase and let the struggle over it continue.

Concealment and recovery

Nanao’s account of the case places it amid the danger already surrounding the train. Back in the first row of car four, he has heard from Maria that the bag’s owner is in car three. He dislikes being so close, but considers anywhere on the train too close and settles on the simplest option: sitting in his ticketed seat. Thinking about Lemon and Tangerine, he wonders whether they are looking for the bag. Their ruthlessness, as described to him by the go-between, makes the case’s presence feel like a threat even before he knows what is inside it.

The hiding place is not an ordinary bin. The Prince tells Kimura that the trash bin is set into a wall panel that opens, concealing a compartment behind it. He takes Kimura to a gangway farther back and indicates a round protrusion on the panel: Kimura must push it, pull, and twist. The panel swings open, revealing the black suitcase on the compartment’s top shelf. At the Prince’s instruction, Kimura reaches in and lifts it out; the Prince then closes the panel neatly. The case’s concealment depends not only on being out of sight but on a hidden mechanism and knowledge of how to operate it.

Lock and contents

The combination lock opens at 0600. Kimura reaches the correct setting quickly, and the click interrupts his recollection; he attributes the speed of the discovery to the Prince’s apparent luck. When Kimura hoists the suitcase onto the toilet and opens it, he finds neatly stacked sheaves of 10,000-yen notes. The bills are used and wrinkled. Although there is a fair amount of money, Kimura is unimpressed: he has transported far larger sums in the past, so the cash does not move him much.

The more consequential discovery is tucked into the webbing inside the case. Kimura finds five debit cards, each from a different bank, with PINs written on the backs in permanent marker. When the Prince later opens the suitcase again, he checks the same webbing and sees the five cards, each marked with a four-digit number. He guesses that the numbers are withdrawal codes; Kimura agrees that this is probably their purpose and observes that the arrangement offers two forms of payment, cash and card. The cards change the meaning of the case: its value is not exhausted by the visible money, and the written codes make the cards immediately usable to whoever possesses them.

The Prince’s handling of the case

After restraining Kimura again with bands and tape, the Prince places the suitcase at his feet and opens it to inspect the notes and cards. Kimura does not treat the cash as a surprise, but identifies the cards as something new. The Prince considers whether using them could let the case’s owner discover where a withdrawal was made. The possibility makes the cards more than a supplement to the cash: they carry a potential trace back to the person or place connected with the account, even as the marked numbers invite their use.

The Prince later dials the lock back to 0600, opens the case, takes the debit cards, and puts them in his pocket. He closes and locks the suitcase and grips it by the handle. The change is precise: he removes the item that interests him while leaving the cash behind. He tells Kimura that he plans to return the case to the panel over the garbage bin, or perhaps leave it somewhere easier to find, such as the luggage rack. He has learned what it contains and no longer cares about keeping the bag; instead, he wants to watch other people who want it fight over it. He also expects that taking the cards will create problems for someone later.

Significance in the train’s struggle

The suitcase’s passage from hidden compartment to open inspection and back toward circulation shifts its function at each stage. Concealed behind a wall, it is a secret to be located; open on the toilet or at the Prince’s feet, it becomes an inventory of cash and encoded access; locked again and carried by its handle, it becomes something the Prince can deploy by choosing where others will find it. The hidden panel initially protects the case from ordinary view, but the people who know how to open it can turn that concealment into temporary control.

The Prince’s decision to take the debit cards but return the case also separates possession from usefulness. He keeps the part he believes may serve him and leaves the visible money and locked container available to fuel competition among other seekers. The object therefore does not settle the conflict when its contents are revealed. Instead, inspection gives the Prince enough information to alter the contest: the suitcase can be put back, perhaps in a more conspicuous place, while the missing cards create a further complication. Its significance lies in that unstable circulation as much as in the money it holds.
