THE PROBLEM
Archie Thomas weekday electronics case
Archie wants relief from a household rule that completely bans weekday electronics while he is already secretly bypassing the rule.
BOOK 3 • CASE MAP • SPOILER-LIGHT ARCHIVE GUIDE
The third Dewey Fairchild book does not contain one giant sibling problem. It contains a sequence of cases that teach Dewey how differently sibling conflict can work—and how often the visible fight is not the real problem.
CASE 01 • OFFICE FILE
Archie wants relief from a household rule that completely bans weekday electronics while he is already secretly bypassing the rule.
THE PROBLEM
Archie wants relief from a household rule that completely bans weekday electronics while he is already secretly bypassing the rule.
THE INTERVENTION
Dewey coaches Archie through admitting his secret weekday gaming and later helps him frame the family discussion around questions intended to distinguish ordinary gaming from a more serious problem.
THE OUTCOME
Naomi moves from immediate punishment into questioning and negotiation, and the family replaces the total ban with a compromise allowing some weekday games and social media so long as use is no longer secret.
FOLLOW-ON CASE
The revised Thomas-family computer routine unintentionally increases Naomi's social-media participation. Angelica experiences her mother's likes, comments, old photographs, and public household questions as intrusive and embarrassing. Naomi learns Minecraft from Archie, becomes absorbed in a game he enjoys, and the family shifts from embarrassing social-media participation toward a more collaborative technology activity; Angelica no longer faces the same online intrusions.
DEWEY'S METHODS
Structured client intake • Environment and access planning • Delegated evidence capture • Controlled disclosure and confession • Iterative solution revision • Shared-interest substitution
CASE 02 • OFFICE FILE
Claire says Adam will not leave her alone. Dewey observes repeated teasing, boundary violations, pranks, intimidation, and retaliation between the siblings.
THE PROBLEM
Claire says Adam will not leave her alone. Dewey observes repeated teasing, boundary violations, pranks, intimidation, and retaliation between the siblings.
THE INTERVENTION
Dewey and Clara conclude that the siblings need a common cause that places them on the same side. Dewey's staged bicycle-theft/ransom plan is intended to manufacture that shared problem, but it escalates when Claire's father discovers the apparent theft and prepares for a real police report.
THE OUTCOME
The staged crisis becomes a genuine common problem. After learning what happened, Adam offers to take the blame and punishment to protect Claire; Claire promises to stand by him. Dewey recognizes that the shared-cause strategy has produced real cooperation and solidarity.
DEWEY'S METHODS
Structured client intake • Environment and access planning • Remote live observation • Physical stakeout • Cover story • Delegated evidence capture • Controlled disclosure and confession • Common-cause alignment • Manufactured shared problem • In-story research as analogy and prompt • Self-regulation before reframing
CASE 03 • OFFICE FILE
Julie and Charles report near-constant fighting between Efren and Louise. Observation shows that Louise repeatedly seeks access to Efren and his possessions while Efren tries to exclude her and protect his space, producing escalating retaliation.
THE PROBLEM
Julie and Charles report near-constant fighting between Efren and Louise. Observation shows that Louise repeatedly seeks access to Efren and his possessions while Efren tries to exclude her and protect his space, producing escalating retaliation.
THE INTERVENTION
Dewey reframes the apparent possession and privacy fights as a mismatch between Efren's desire for space and Louise's desire for attention. He proposes a prevention strategy: Efren should give Louise a short period of focused time so she is less likely to intrude later.
THE OUTCOME
Julie and Charles respond positively to the plan. Two weeks later they are satisfied enough with the result to offer Dewey payment, which he declines because he views problem solving as a craft rather than a paid service.
DEWEY'S METHODS
Structured client intake • Environment and access planning • Physical stakeout • Underlying-motive reframing • Focused-attention prevention • In-story research as analogy and prompt • Collaborative consultation • Confidentiality adaptation
CASE 04 • OFFICE FILE
As Dewey begins solving sibling problems professionally, Pooh Bear and Stephanie discover or enter his hidden office, forcing him to confront sibling boundaries and the fragility of the office secret inside his own family.
THE PROBLEM
As Dewey begins solving sibling problems professionally, Pooh Bear and Stephanie discover or enter his hidden office, forcing him to confront sibling boundaries and the fragility of the office secret inside his own family.
THE OUTCOME
The thread ends not with Dewey containing the secret but with Pooh Bear, Stephanie, Karen, and Don all sliding into the office; Pooh Bear triumphantly confirms that her account of the hidden office was true.
METHOD MAP • CLARA'S NOTES
Clara has filed the moves Dewey keeps reaching for when a sibling case gets messy.
intake_and_classification
Dewey and Clara use forms and categorized records to define the client's problem, identify family members, map relevant household details, and sort requests into problem types.
fieldwork_planning
Before observing a household, Dewey studies entry routes, alarms, hiding places, family routines, and physical constraints so he can choose an observation position without being detected.
surveillance
Dewey initially tries to observe Claire and Adam remotely by having Claire start a live video connection whenever Adam is nearby, including moments when no conflict is yet occurring.
surveillance
When remote or reported evidence is inadequate, Dewey hides inside a client's home or vehicle and directly observes family behavior while taking notes.
operational_concealment
Dewey uses an ordinary-sounding explanation for his movements when covert casework would otherwise expose the investigation.
distributed_investigation
When Dewey cannot directly access evidence, he asks a client or collaborator to capture material for him, such as screenshots or live video.
behavior_change_intervention
Dewey sometimes moves a case forward by having a client admit hidden behavior or reveal an uncomfortable truth, accepting that the immediate reaction may be worse before the larger problem can be renegotiated.
design_iteration
Dewey treats a solution as revisable when it creates a new problem instead of defending the original plan as final.
relationship_repair
Instead of merely suppressing an unwanted family behavior, the Thomas-family solution redirects Naomi toward a shared activity—Minecraft—that creates connection with Archie without reproducing Angelica's social-media boundary problem.
sibling_relationship_intervention
Clara and Dewey reason that siblings who are fighting may become allies if they face a shared problem that makes cooperation more useful than attacking each other.
experimental_intervention
Dewey operationalizes the common-cause idea by staging Claire's bicycle disappearance and a ransom trail so Adam and Claire will have a problem to solve together.
Caution: The intervention develops an unplanned real-world complication when Claire's father prepares to report the apparent theft to police.
case_analysis
Dewey separates the visible object conflict from the underlying need. In the Disk case he realizes Louise's behavior is less about possessing Efren's Lego than about wanting access to and attention from Efren himself.
sibling_relationship_intervention
Dewey proposes that Efren proactively give Louise a short period of focused attention so her need for connection is met before it turns into later intrusion, possession conflict, or retaliation.
research_and_reframing
Dewey uses material he encounters during research not as unquestioned external truth but as prompts, analogies, and conceptual tools for thinking about a case.
solution_delivery
During the Disk follow-up, Dewey discovers that presenting a solution can itself be collaborative: the adult clients help interpret an analogy and articulate parts of the recommendation with him.
business_process
When adults become clients, Dewey adapts the office's paperwork and adds an explicit confidentiality agreement rather than assuming the child-client workflow will work unchanged.
problem_solver_self_management
When the Claire-and-Adam plan begins to collapse, Dewey deliberately slows his breathing before reinterpreting the crisis as the genuine shared problem the siblings need.

Book 1 creates the parent-problem method. Book 2 pushes it into school and teacher systems. Book 3 turns the same logic toward siblings—and back toward Dewey's own family again.
