Cases Three, Four, Five and Nine — the campaign is complete

Thirteen cases, all playable, all lint clean, all verified end-to-end at
100/100 (Case One is 95 + 5 optional by design).

Case Three — Rendezvous at Big Gulch. The racket only shakes down businesses
that are doing well, so to get extorted you must run a genuinely excellent
locksmith shop. Frank reads MODERN LOCKSMITHING cover to cover and retains all
of it while understanding none of it, which for locksmithing is the correct
ratio. The street won't talk because paper doesn't stand in your doorway on a
Friday; Halloran opens up only after you offer to fix his door, and his
extortion ledger has been lying open on a public counter for two and a half
years because nobody ever asked to see his book.

Case Four — Revenge and Remorse. Section 14 paragraph 9 was written in 1949 for
a 1949 timer, and this bomber files his timing stub twice because he cannot
leave a thing not-quite-square, which shortens the contact throw and energises
the trigger first. Follow the manual and it completes. So Frank disarms it
backwards — the one time in nineteen years he departs from a written
instruction, because he can prove the instruction is wrong in four sentences.
Carries PQ1's Captain loop and an explicit refusal of PQ3's centre-pixel bug.

Case Five — The Butler Did It. Chain of custody on a birthday cake: photograph,
weigh with a witness, seal all forty forks. Eleven pounds light in the tier
nobody cuts, because she was inside it for four minutes while forty people
looked at it. And Frank will not suspect the butler because the literature says
it is always the butler, so suspecting him would be quoting rather than
investigating. It is the butler.

Case Nine — The Final Insult. The marriage is a gate, not a subplot: the finale
is locked behind actually answering the counsellor's question, and Jane's terms
are "before you go, not after". He doesn't disarm the envelope, he swaps it and
writes in a winner by hand. He picks the one he liked.

Two point budgets came in over (110, 115) and are trimmed to exactly 100.
Sprite generation needed a kill-and-restart: two overlapping runs were competing
for the farm and producing "Resource temporarily unavailable" — one clean pass
at pool 2 completed all four sets with zero failures.

He wheeled her out in her own cake because she asked him for a trick to play on her father. Then, at nine o'clock, entirely on his own, he cut forty-one letters square out of the Tribune and pasted them on a sheet of paper and left it on the step, for two hundred thousand dollars, from a man who has not got two hundred dollars, so that Cornelius Vane would have to stand in his own hall in front of forty people and find out what it feels like to be about to lose something.  He never intended to collect. There is nowhere in the note to send it.  You arrest him and advise him of his rights in the correct order and in full, and he thanks you, and he puts the tray down first, because you do not go anywhere holding a tray.  On the way out he says the only thing he says all night that is not an answer to a question: 'You were the only one who never once looked at me. Thirty-one years and I have never been so nearly invisible in my life.'  You tell him you had read that it is always the butler and had therefore decided it could not be, and that this was, on reflection, the single stupidest professional decision of your career.  He says: 'It usually is us, sir. There are simply not very many of us left.'  Somewhere below, forty guests are still in the ballroom, and Officer Al says something, and everybody laughs, and everybody freezes, smiling, holding it — except a twelve-year-old at the top of the house, who is asking, again, whether her father is laughing yet.
