Chapter Summaries

Professor Sprout interrupted Snape and McGonagall’s dispute by revealing Douglas’s reckless prank as a student, dissolving the confrontation in laughter. A Ministry owl then delivered an invitation for Douglas to join the Triwizard Tournament Committee as Special Rules and Safety Adviser for the second task.

• Harry watched Snape argue with Douglas and grew more convinced that Snape was up to something, while Hermione worried Harry was being led astray.
• Professor Sprout stepped between Snape, McGonagall, and Douglas, then recalled how Douglas had tricked Bill Weasley and Charlie Weasley into approaching a mature Mandrake.

• Douglas admitted that his prank had been wrong, and the laughter brought the argument to an end.
• A Ministry owl delivered Dumbledore a letter inviting Professor Douglas Holmes to serve as Special Rules and Safety Adviser for the Triwizard Tournament’s second task.

Douglas Holmes proposed turning the Black Lake’s second-task venue into an underwater maze and secured control over its design through a secrecy agreement and an outside contract. The meeting ended with Sirius coordinating construction and Percy preparing the official report.

• Douglas proposed adding magical mechanisms and creatures to the underwater task while keeping its objective of retrieving something precious unchanged.
• Douglas introduced a Gringotts-drafted confidentiality agreement, which he, Dumbledore, Karkaroff, Madame Maxime, and Percy signed.

• The committee assigned Douglas control of the second task, Sirius responsibility for construction coordination, and Percy responsibility for the official report.

After Douglas took charge of the second task, Percy told Karkaroff to move the Durmstrang ship, and Karkaroff used powerful alchemy to lift it from the Black Lake. Seeing the preparations, the champions feared what Douglas was planning and agreed to meet; the chapter ends with them preparing to work together.

• Students learned that Douglas would personally design a harder second task, and Cedric, Krum, and Pheobe realized he might be their real opponent.

• Karkaroff refused Hogwarts’s help and used an alchemical array to raise the ship from the lake and set it beside the Quidditch Pitch.
• Fleur, Krum, and Cedric feared the scale of Douglas’s plans, and Cedric proposed that the champions meet instead of working alone.

Cedric, Fleur, and Krum formed an alliance to prepare for the second task, while Moody focused on the third task and his trap for Harry. At Hogwarts, Hermione redirected the Charon Detective Agency from investigating the Black Lake project, and the twins gave the club a new assignment to investigate the champions.

• Cedric, Fleur, and Krum agreed to share underwater magic and help one another if any champion faced danger they could not handle alone.
• Moody watched the champions' meeting and worried that Douglas's involvement in the second task might affect the third task, where he planned to trap Harry.

• Moody dismissed the Detective Club’s new mission and urged Harry to investigate Snape and Karkaroff’s meetings, claiming they were connected to a man from the past.
• Hermione saw that the club members were eager to investigate the champions, while Ginny noticed Hermione’s strain and asked whether she was hiding something.

Sirius Black and the merpeople chieftainess Muriel negotiated after the Marauders Power Company’s work damaged the Black Lake and Ancestors' Reef. They reached a deal that brought the merpeople into the Triwizard Tournament’s Second Task and made them temporary partners in the construction project.

• Remus Lupin directed werewolf workers while Sirius Black argued with Professor Flitwick over increasing the project’s magical output.
• Muriel arrived with merpeople warriors and accused the company of damaging Ancestors' Reef and breaking its agreement with the merpeople.
• Dumbledore apologized and promised to halt work around the reef, but Muriel rejected Sirius’s offer of goblin-made tridents as compensation.

Douglas Holmes framed the Daily Prophet’s coverage of the werewolf workers as marketing, while Sirius and Douglas used the publicity to strengthen their position with the Ministry. Douglas then began a Defense Against Dark Magic lesson on maintaining focus in a dangerous environment, ending as he introduced the next subject.

• Fred and George told Douglas Holmes that parents were protesting the werewolf workers and that the workers felt discouraged, but Douglas said the newspaper coverage was planned marketing.
• Lupin saw himself and his companions portrayed as builders in the Daily Prophet and stood straighter.
• Sirius received Scrimgeour’s angry letter demanding an explanation for publicizing the company, along with a request for a Ministry atrium security-upgrade quotation.
• Sirius and Douglas agreed that the Marauders Power Company had become an independent commercial entity and that the Ministry would have to work with it.
• Douglas tested the class on the Summoning Charm, then created an illusion of the Black Lake and taught the students to use breathing to cast the Calming Charm.
• After Douglas dispelled the illusion, he announced the second subject.

Douglas taught the students how to defeat Abyss Soul-Sucking Algae by striking its magical heart during a brief lapse in its defenses, then compared several ways to breathe underwater. After class, Cedric, Pheobe, and Krum feared that Douglas’s lessons were only basic preparation for a much harder competition.

• Douglas summoned Abyss Soul-Sucking Algae and explained how its magical heart powered its attacks and disrupted spells.
• Douglas demonstrated that a precisely timed Piercing Charm could strike the plant’s core during the gap between heartbeats and disable it.
• Douglas compared the Bubble-Head Charm, Gillyweed, and Transfiguration as methods for breathing underwater, warning the students about each method’s risks.
• After class, Cedric, Pheobe, and Krum met in an abandoned classroom and concluded that Douglas’s lessons were only an entry-level preparation for his competition.

Dumbledore summoned Douglas Holmes to discuss how to motivate Hogwarts students after their monthly exams, and the two devised an individual ranking system based on wisdom points. They began designing rewards for the points, leaving the top-tier prizes undecided.

• Dumbledore studied Muggle educational theories and summoned Douglas Holmes with his Mother-and-Child Summoning Bell to discuss students’ lack of motivation.
• Douglas proposed turning Dumbledore’s individual points system into a competition of wisdom and prestige, and Dumbledore agreed.
• Dumbledore and Douglas created rules for earning wisdom points through class performance, assignments, submissions to the Hogwarts Academic Weekly, and academic assistance.

• Douglas proposed a monthly wisdom-points reward of a private dinner with Dumbledore and a year-end reward of Wizard’s Chess.

• Douglas suggested combining wisdom and prestige points into team totals that champions could spend on clue blind boxes for the second task.
• Douglas explained how the rules would appeal to Karkaroff and Madame Maxime, and Dumbledore agreed to begin the reform.

Fred and George unveiled a tiered blind-box shop where students could spend their teams’ combined points on clues for the underwater maze. They ended by offering a 2,000-point advance in exchange for a magical contract with a professor, as Hermione identified the Twins’ sales tactics as schemes.

• The magical screen showed Cedric Diggory's team leading with 4,350 points, ahead of Fleur Delacour's team and Viktor Krum's team.

• Hermione recorded the blind-box offers as sales schemes, while the Twins invited students to sign a magical contract with a professor to receive the advance.

Cedric Diggory followed Hermione’s advice and spent 2,500 points on twenty-five bronze mystery boxes, which yielded two B-grade clues and twenty-three C-grade clues. Hermione secured the sealed scrolls and took Cedric back for a team meeting without opening them in the Great Hall.

• Malfoy urged Krum to gamble most of their points, but Krum expressed his aversion to gambling.

Krum followed Malfoy’s urging and spent two thousand points on a Golden Blind Box, but received only an A-Rank Clue, leaving Malfoy humiliated. As the first clue exchange ended, Harry felt excluded from the competition, while Hermione focused on analyzing her clues to catch up with Pheobe.
