Disciplined from the first question to the final report.

We seek to understand the matter sufficiently to assess urgency, fit and immediate risk — without inviting unnecessary sensitive information. Where danger, evidence loss or a legal deadline is present, we say so immediately and advise who else should be engaged.

Output Intake record, priority classification and next-step instruction.

Gate Blackthorn has not yet accepted the matter.

We verify the instructing client or organisation, identify the parties for conflict checking, and screen for malicious, retaliatory, coercive or unlawful intent. We also consider whether the subject is represented, protected or otherwise sensitive.

Output Conflict result, client verification record and an accept, clarify, refer or decline decision.

Gate No operational work begins until suitability is confirmed.

We record the client’s relationship to the matter and its legitimate purpose, then assess privacy and personal-information implications, special or children’s information, employment and surveillance issues, and cross-border considerations.

Output Authority and lawful-purpose record, method restrictions, privacy requirements and legal escalation items.

Gate If the work cannot be done lawfully and ethically, we decline it or redesign it.

A concern becomes a clear, testable and commercially controlled assignment. Allegations are converted into specific issues, scope and exclusions are defined, and deliverables, evidential standard, budget, milestones and change control are agreed.

Output Engagement letter, investigation plan, issue matrix, budget and timeline assumptions.

Gate The client approves the mandate before collection begins.

Client-held material is received through approved secure transfer, recorded by source and date, and preserved in original form where relevant. Duplicates, missing records and potential alteration are identified early.

Output Evidence register, initial chronology, preservation risks and information gaps.

Only approved methods are used: documentary review, corporate and public-record research, open-source intelligence, address and scene verification, subject location, interviews, network analysis, asset-indicator research and — where lawful and proportionate — surveillance.

Output Collection log, source records, field and interview material, progress updates and emerging-risk alerts.

We resolve identity and attribution, compare independent sources, and test documents, statements, observations and digital material against one another. Contradictions and alternative explanations are actively sought rather than avoided.

Output Verified fact set, discrepancy matrix, confidence assessment and updated issue findings.

Names, dates, amounts, entities and sources are checked, and conclusions are tested against the evidence that supports them. Privilege, privacy, redaction and distribution instructions are applied before release.

Output Quality-approved report, restricted annexures where applicable and a defined distribution list.

Findings are delivered securely and briefed to authorised decision-makers, with confidence levels, limitations and alternative explanations explained. Investigation recommendations remain separate from legal, HR, claims and governance decisions.

Output Final report or intelligence brief, executive briefing and action log.

The matter is closed securely and only what must lawfully or contractually be retained is kept. Evidence is returned or transferred, temporary access is revoked and recurring risk indicators are captured.

Output Closure record, retention schedule and a follow-up proposal where justified.
