It's a covert game of cat and mouse set on the streets of London! Criminal mastermind Mister X has escaped Scotland Yard and it's up to you, the detectives, to catch him! Use your travel tickets to anticipate his movements, chasing him by taxi, bus, and underground, around Picadilly Circus, along the River Thames, and through Paddington Station. Will you apprehend this dangerous criminal or will he disappear in the London fog?

Setup

First decide who will play the role of Mister X!

Mister X Receives:

- 1 transparent playing piece

The Mister X visor which will help conceal his gaze to avoid giving up any secrets:

- 1 Travel Log

- 1 Pencil (not included)

- 1 Black Ticket

- 1 Double-Move Ticket

13 rounds are played.

In each round, Mister X first makes his move. Once Mister X has completed his turn, the detectives take their turns in any order.

All detectives share the same goal: catching Mr. Mister X either by one of them finishing their move on the same station as Mister X or blocking all stations with detectives leaving no free station for Mister X to move to.

Mister X disappears in regular intervals and is invisible for a round. Before his 3rd, 8th and 13th moves he removes his playing piece from the game board and secretly records his next destination.

The detectives win the game if:

- A detective finishes his move on the same station as Mister X. If Mister X happens to be invisible at that time, he has to show himself.

- Mister X has no free stations the he can move to. All possible stations are blocked by detectives

Mister X wins, if:

He manages to travel across London for 13 rounds without being caught by the detectives. The round is only over once the detectives have also completed their moves.
