BASE PRICE
The starting amount for a defined part of the offer.
THE FIRST SCENT
A number appeared on the screen.
Then another number appeared after sign-in, at checkout, on the card, or at the end of the journey.
Perhaps the first number was wrong.
Perhaps the second number described something different.
Dame Kitty Holmes would like to inspect the labels before arresting either one.
THE NUMBER CHANGED. FIRST ASK WHETHER ITS JOB CHANGED TOO.

THE CLUE
A traveler may first see a base price, a displayed total, a signed-in rate, a deposit, an authorization, an amount due later, or a final charge.
Those numbers may belong to the same journey without doing the same work.
One may introduce the option. Another may reserve it. Another may temporarily protect the business from risk. Another may record what was finally delivered.
The useful question is not only, “Why did the number change?”
It is also, “What was this number responsible for at that moment?”
SAME JOURNEY. DIFFERENT MOMENT. POSSIBLY A DIFFERENT JOB.
THE FIRST TEMPTATION
Two unequal numbers placed close together can feel like a contradiction.
Sometimes they are. Sometimes a condition changed. Sometimes one number included something the other did not. Sometimes the journey simply moved to another stage.
Before deciding what the difference means, Dame Kitty checks whether the numbers describe the same dates, people, conditions, inclusions, currency, moment, and obligation.
That is less dramatic than pouncing.
It is also more useful.
EXHIBIT A — A FICTIONAL EXAMPLE
A search result displayed a room at $249.
The rate details showed that taxes and a city fee were not yet included.
Checkout requested a deposit and explained that the remaining amount would be due at the property.
The card record later showed a temporary hold for incidentals.
The final receipt reflected the room, the stated charges, and one service used during the stay.
Each record contained a number. The numbers were connected, but they were not interchangeable.
THE FIRST NUMBER OPENED THE DOOR. THE LATER RECORDS SHOWED MORE OF THE ROOM.
THE WARDROBE
The starting amount for a defined part of the offer.
The amount a particular screen presents within its stated scope.
A price available only after a stated membership, identity, residency, age, loyalty, or eligibility condition is met.
Money collected now toward a larger obligation or to secure the booking.
A temporary approval or hold that may reduce available funds without yet becoming the final charge.
Part of the known obligation scheduled for another stage of the journey.
The amount ultimately collected for the value, changes, and conditions recorded at completion.
A CURRENCY SYMBOL TELLS YOU THE UNIT. THE LABEL TELLS YOU THE JOB.
THE COMPARISON TEST
A different day, season, duration, or booking moment may change the offer.
Age, occupancy, residency, membership, and eligibility can alter what applies.
Similar descriptions do not always establish the same inventory or terms.
Flexibility can carry value and cost even when the visible product looks alike.
Meals, baggage, transfers, taxes, fees, equipment, or services may sit inside one number and outside another.
The symbol, conversion basis, and card-processing currency all matter.
One record may include them while another identifies them separately or defers them.
A quote, reservation, authorization, change, completion, and final receipt belong to different stages.
COMPARE THE CONDITIONS. THEN COMPARE THE NUMBERS.
THE RECORDS
What option was made visible, and within what stated scope?
What did the offer include, exclude, require, or leave conditional?
What was selected, what became due, and when?
What did the business record as accepted or promised?
What amount was authorized, collected, released, or refunded?
What did the completed journey ultimately record?
No single document must be forced to answer a question that belongs to another record.
THE HONEST QUESTION
Did the business clearly identify what each number meant?
Could the traveler reasonably understand what was included, conditional, due now, or due later?
Did the later record reflect a disclosed change, an additional choice, a temporary hold, or something still unexplained?
Which document can responsibly answer the next question?
Curiosity does not require suspicion. It requires enough patience to keep the known, the unknown, and the merely assumed in separate drawers.
CURIOSITY OPENS THE CASE. THE RECORD DECIDES WHERE IT GOES.
DAME KITTY’S FINDING
The first number may have been an invitation to look.
The next may have reflected eligibility, selected conditions, a deposit, a hold, an amount due later, or the completed record.
That does not prove every difference was correct.
It does show why the labels, conditions, timing, and records must be compared before the numbers are asked to agree.
THE NUMBER MOVED. DAME KITTY CHECKED WHAT MOVED WITH IT.
A QUESTION TO TAKE WITH YOU
Is it introducing the offer?
Is it describing the selected conditions?
Is it collecting part of the obligation?
Is it temporarily holding funds?
Is it recording what finally happened?
The answer may not close the case.
It will tell you which drawer to open next.
CASE FILE 01 — FINDING RECORDED
Some price differences reveal an error. Others reveal a condition, a stage, an inclusion, a timing difference, or a record doing its own particular work.
Dame Kitty Holmes has returned the labels to the wardrobe.
For now.
CASE OPENED BY CURIOSITY. CONCLUSION RESERVED FOR THE EVIDENCE.
