01 THE INVITATION
Don’t just read
the mystery.
Step inside it.
There’s a moment when a detail stops being a detail.
A timestamp. A missing line. An alibi that fits a little too well.
Detective Night turns that moment into your evening. Each original case is a self-contained investigation, with written evidence, four suspects, and a conclusion you must justify.
No searching the internet for the answer. No specialist knowledge to bring along. The rules and records you need are inside the dossier.
See what’s inside a caseYour next night together
Share the dossier, debate the evidence, and agree on your final accusation.
Your curious side
Work through changing difficulty levels, from your first case to layered evidence chains.

08 BEFORE YOU OPEN THE FILE
A FEW ANSWERS, WITHOUT THE SPOILERS.
Curious?
You should be.
Here’s what to know about the format, the challenge, and choosing your collection.
Return to the collectionsWhat exactly is Detective Night?
A collection of original, fictional mystery games delivered as English-language PDFs. You investigate written evidence and answer six final questions, then compare your reasoning with a separate solution. The enchanted archive is the visual setting of this website; the investigations are grounded deduction stories.
What do I receive with a case?
Four files: an Investigation, a fillable Notebook, progressive Hints, and a separate Solution. Every collection also includes the Start Here and Group Play guides. The five featured cases each have a 17-page Investigation, a 3-page Notebook, 4 pages of Hints, and a 7-page Solution; page counts may vary across the full collection.
How many mysteries are ready?
All 20 mysteries are complete. You can purchase a finished collection containing 1, 3, 5, 8, 12, or 20 cases. The five illustrated previews on this page introduce the opening batch; they do not represent the full archive.
Are the files in English?
Yes. The investigations, clues, notebooks, hints, solutions, and guides are in English. A different-language edition is not currently part of these collections.
Can I play alone or with other people?
Both. Work through the records solo, or investigate together in a personal game session. The Group Play guide explains how to share the evidence, manage hints, and reach a joint verdict. No actor or outside game master is required.
How long does an investigation take?
The five featured case previews have estimated sessions of 45–100 minutes. Playing time varies by case and by your pace. They are not timed challenges. Pause, revisit a record, and continue when you want.
Do I need an app, printer, or special knowledge?
You need a device that can read PDFs, or printed reader materials. No separate game app, internet research, external audio, electronics knowledge, or botany knowledge is required. The fictional systems and their rules are explained in the supplied evidence.
Can I fill in the notebook digitally?
Yes, the notebook has fillable PDF fields. Use a PDF reader that supports form filling and save a copy of your work. Browser PDF viewers vary in form support; printing the notebook and writing by hand is also an option.
What if I get stuck or accidentally see a spoiler?
Hints offer three progressive levels. Open one level at a time when you need a nudge. The solution is a separate file, clearly marked for spoilers. Keep it closed until you have committed to your final answers.
Which collection should I start with?
Choose First Case for a single introductory evening, Opening Trilogy for three cases with increasing complexity, or Midnight Collection for the entire completed first batch. Choose Extended Archive for 8 cases, Collector’s Library for 12, or Complete Archive for all 20. All six collections contain finished files.
Is this a subscription? Can I replay the cases?
The displayed offers are one-time digital collections, not subscriptions. You can revisit your files, but knowing the solution changes the challenge: a case is best treated as one fresh deduction experience, then a story to review.
How do delivery, refunds, and support work?
After confirmed payment, your collection is delivered by email, with no download deadline. Our standard refund period is 7 calendar days from receipt of the materials; applicable mandatory local consumer rights can provide additional protection. Contact Suport@detectivenight.lat during Brazilian business hours (Brasília time). Read the delivery information and refund policy below. Online purchase availability is shown for each collection.
LEAVE THE ORDINARY EVENING BEHIND.
The evidence is waiting.
So is your first case.
Twenty original mysteries. Four files per case.
One evening that might end with “I knew it.”

Refunds, withdrawal & disputes
CLEAR RIGHTS BEFORE YOU PAY
Our standard refund window
Our standard withdrawal and refund period is 7 calendar days from receipt of the purchased digital materials. For distance purchases governed by Brazilian consumer law, the withdrawal rights and repayment obligations of Article 49 of the Brazilian Consumer Protection Code apply.
For purchases outside Brazil, applicable mandatory consumer law may provide a longer period or additional rights. Those protections take precedence where they apply. This policy does not reduce, waive or replace statutory consumer rights, including rights relating to non-delivery, defective files or an incorrect charge.
How to request a refund or cancellation
Email Suport@detectivenight.lat with the email address used for the purchase, your order reference, collection name and a clear request to cancel or receive a refund. Giving a reason is optional when exercising a statutory right of withdrawal. We may ask for information needed to identify the order and verify the request.
Eligible refunds are initiated promptly in accordance with applicable legal deadlines. The original payment method is used where supported; bank or payment-provider processing times may vary. If that method cannot accept a refund, we will arrange a lawful alternative with you.
Delivery problems and incorrect charges
Contact us about missing materials, damaged files, an incorrect collection, duplicate charges or suspected unauthorized payments. We will review the issue and provide the appropriate correction or refund under the purchase terms and applicable law. Mandatory remedies can remain available after the standard 7-day period.
Billing disputes
You can contact us to resolve a billing concern. This does not prevent you from contacting your bank, card issuer or payment provider, or using any formal complaint or dispute procedure available to you. We do not require you to waive those rights in order to receive support.
