Inspector Marchetti has done the legwork: doors knocked, statements taken, notebook filled. What she has not done is put it together. That part is yours. Four steps, one pen, no knowledge of Paris needed.
Every witness gives you one fact. None of them lies. Each fact rules out part of the city.
Hatch the districts the clue eliminates on the printed map of Paris.
Six real streets per arrondissement. Cross the ones that no longer fit.
Numbers 1 to 120 on every street. Keep going until a single door survives, then check the verification code.
20 genuine arrondissements with their official boundaries. 120 famous streets, six per arrondissement. 14,400 house numbers to cross out. Every clue is printed on the page: rive gauche or rive droite, along the Seine or by the périphérique, a street named after a saint, a number divisible by seven.
Each case comes with its own printed grid of Paris, so you can mark the book up freely. Sixteen statements per case, about two hours each, and exactly one answer, checked by an independent solver before printing.
A baker with a six-month waiting list, found on a Sunday morning. The bread came out. He did not.
2.3 million followers, one beige apartment, and a Monday with no post.
A founder, a natural wine bar, 140 guests and one missing host.
6 × 9 inch paperback, matte cover, white paper made to take a pen. The city is printed three times, once per case.
Paperback, printed on demand and shipped by Amazon. Pick your store.
Also on Amazon.ca, .com.au, .it, .es, .nl and .co.jpEvery case is generated and then re-solved by an independent solver before it goes to print, which means the logic always holds: one solution, no guessing, no dead ends, no case that falls apart on page forty.
The Murder Map series hides a single killer somewhere in a real city and hands you the witness statements, the street grid and about two hours per case.
