Chapter 01
The Case for Public Hiding
Core Concept
The fundamental problem: hiding valuables at home is risky. Burglars, nosy roommates, and family members all have access. The solution? Secrete your possessions away from home. The world around us is filled with cubbyholes and niches that can be safely employed—if you know where to look and how to use them.
This chapter establishes the mindset: you are not looking for a permanent vault, but a temporary, deniable, and accessible location that blends into the environment. The public world is your private storage locker.
Key Insight: The best hiding place is one that no one else wants to touch, look at, or clean. The more mundane and unappealing, the better.
Chapter 02
Principles of Public Hiding
Core Concept
Fiery lays out the foundational rules that govern all successful public hiding. These principles separate a amateur stash from a professional dead drop.
Blend In: The container and its location must look like they belong. A package hidden behind a dumpster is suspicious; a package that is part of the dumpster's clutter is invisible.
Accessibility & Deniability: You must be able to retrieve the item quickly and without drawing attention. Your actions should have a plausible reason if questioned.
Weather & Durability: The environment is hostile. Moisture, temperature, and pests will destroy improper containers. Proper sealing is non-negotiable.
The "Touch" Factor: Avoid places that are regularly maintained, cleaned, or inspected. High-traffic areas are good; high-interaction areas are bad.
Memorability: You must be able to find it again. Use landmarks, but not ones that change.
Chapter 03
More Principles & Strategies
Core Concept
Advanced techniques for the serious practitioner. This chapter covers the psychology of hiding and the importance of compartmentalization.
The Decoy: Sometimes, a visible, easily found stash will satisfy a searcher, protecting the real location.
Multi-Stage Retrieval: For high-value items, use a two-part system. A small, obvious container holds a clue or key to the real, much better-hidden location.
Routine & Timing: Retrieve and deposit items at consistent, but not suspiciously regular, times. Avoid patterns that can be observed.
Tool Kit: Carry a small, innocent-looking kit (multi-tool, tape, marker) that allows you to create or modify hiding spots on the fly.
Warning: Never hide items in locations that are too perfect. A completely empty, clean shelf in a grimy alley is an anomaly. Embrace clutter.
Chapter 04
Containers, Dead Drops & Miniatura
Technical
This is the hardware chapter. Fiery details the tools of the trade, from simple containers to the concept of "miniatura"—the art of hiding items in plain sight by making them miniature or disguising them as everyday objects.
Improvised Containers: PVC pipes, magnetic key holders, hollowed-out bolts, and fake rocks. The key is watertight sealing and corrosion resistance.
The Dead Drop: A location used to transfer items without direct contact. The book extensively covers the methodology of the dead drop, including signaling and retrieval techniques.
Miniatura: Creating or using tiny versions of items. A micro-SD card is easier to hide than a laptop. This also includes hiding items inside other innocuous objects (e.g., a hollowed-out book, a false-bottomed can).
Simplex Locks: The appendices include combinations for these mechanical push-button locks, often found on public storage boxes, utility panels, and even some dumpsters. Knowing common combinations can grant access to secure, pre-existing "containers."
Chapter 05
Landscape & Hiding Around the Home
Urban & Suburban
Your immediate environment is the first place to master. This chapter covers hiding spots that are just outside your door, in the yard, or in the immediate neighborhood.
Landscape Features: Loose bricks in a wall, under particular rocks, inside decorative garden lights, or buried in planters. The key is to never disturb the soil in a noticeable way.
Around the Home: The exterior of your own home is a goldmine. Behind loose siding, under the eaves, inside a gutter downspout (if sealed), or in a vent.
The "Mailbox" Principle: A location that is frequented by others (like a community mailbox) but not inspected can be ideal. A package left near but not in a mailbox is often ignored.
Chapter 06
The Street & Other Urban Areas
Urban
The classic public hiding environment. The street offers a massive array of options, from the grimy to the clever.
Trash & Recycling: The ultimate camouflage. A sealed container inside a larger, disgusting bag of trash is rarely touched. The book warns about sanitation schedules and scavengers.
Street Furniture: Beneath benches, inside the bases of lampposts (if accessible), behind bus stop signage, or under the lip of a newspaper box.
Construction Sites: High-risk, high-reward. A stash in a pile of materials must be retrieved before the site changes. Requires precise timing.
Signage & Infrastructure: Behind loose "No Parking" signs, inside the hollow posts of traffic signs, or in utility boxes (requires specific tools).
Chapter 07
Hiding Items with Innocent Bystanders
Social Engineering
This chapter is about using other people and their property as unwitting accomplices. It is the most socially complex form of hiding.
The "Leave Behind": Hiding an item in a location that a bystander will naturally guard or ignore, such as a stroller, a shopping cart, or a pile of belongings at a cafe.
Using the Mail: Mailing an item to a "safe" address (a vacant house, a business that receives high volumes of mail) for later retrieval. This is a form of dead drop.
The "Borrow" Technique: Temporarily hiding an item in a public lending library book or a rental locker. The item is safe as long as the book or locker is not accessed.
Social Camouflage: Dressing and acting in a way that makes you invisible. A construction worker, a delivery person, or a person in a suit all have different levels of access and invisibility.
Chapter 08
Public Buildings & Businesses
Infiltration
Moving indoors. Public buildings offer climate control and numerous hiding spots, but also higher security.
Libraries: The classic. Between the pages of a rarely-accessed reference book, or in the gap behind a bookshelf.
Department Stores: Hiding an item inside another item that is for sale (e.g., inside a tent, a suitcase, or a large jacket on the rack).
Restrooms: The ceiling tiles, behind the toilet tank, or inside the access panel of a sink. High traffic but low scrutiny.
Malls & Food Courts: The undersides of tables and chairs, or in the crevices of booth seating.
Safety Rule: Always check for security cameras. A hiding spot is useless if your retrieval is recorded.
Chapter 09
Specific Public Buildings to Consider
Infiltration
Fiery goes into detail on the unique opportunities and challenges presented by specific types of buildings.
Airports & Train Stations: Lockers (if available), lost-and-found, and the chaos of a departure gate. High security, but high anonymity in crowds.
Hospitals: A place of constant activity, but also areas that are ignored, like the waiting rooms or the chapel.
Universities: A goldmine of accessible buildings, 24-hour libraries, and a transient population that doesn't question unfamiliar faces.
Hotels: The lobby restrooms, the business center, or even a room that is being cleaned. The key is to look like you belong.
Chapter 10
Relaying Messages
Covert Comms
Hiding isn't just about objects; it's about information. This chapter adapts the principles of public hiding to covert communication.
Dead Drop Signals: How to signal that a drop has been made or retrieved. A chalk mark on a mailbox, a particular piece of tape on a lamppost, or a specific arrangement of objects.
Public Anonymous Transactions: The book covers techniques for making exchanges of goods without physical contact, allowing full anonymity for both parties.
Covert Messaging: Hiding a written message in a location for another person to find. This requires a pre-arranged system and a location that is obscure but easy for the intended recipient to find.
Digital Hiding: While the book predates modern smartphones, the principles apply. Hiding a USB drive in a public place is a modern adaptation of the classic dead drop.
Chapter 11
Some Safety Rules
Essential
The final chapter is dedicated to operational security. The best hiding spot is worthless if you compromise yourself.
Never be seen: The act of hiding or retrieving is the most vulnerable moment. Practice in low-risk areas first. Use natural cover. Look like you belong.
Don't hide with others: Never reveal your hiding spot to anyone. The more people who know, the more likely it is to be compromised.
Use gloves: Avoid leaving fingerprints on containers or at the location.
Have a cover story: If questioned, have a plausible reason for being where you are and doing what you are doing. "I thought I dropped my keys" is a classic.
Trust your instincts: If a location feels wrong, it probably is. Walk away and find another spot.
Final Rule: The book is for informational purposes only. Always consider the legal and ethical implications of your actions. Hiding items can be construed as illegal activity if used improperly.
Appendices & Operational Resources
As noted in the original 1996 edition, the book concludes with practical reference materials for the field operative:
