The staff at top secret WW2 code-breaking centre, Bletchley Park, have become suspicious of a spy in their midst, culminating in the discovery of an incriminating letter from the spy which reveals that they’ll be leaving on the 9.05pm train from Bletchley Station to London. The letter tells of several German decrypts the spy has stolen and concealed within the station, ready to flee with. The heads at the park have intercepted the 9.05 train and found seven suspects boarding, whom they have taken back to HQ. They need to find out who the spy is and make sure all stolen decrypts are recovered. Of course Bletchley Park is so secret that no one from the outside world can know about the situation without blowing its cover. Unless…they’re from so far in the future that there the secret has been revealed! That’s where you come in. Secretly drafted in by the heads of Bletchley Park with Professor Potch’s help, you will be assuming the identities of hard-at-work Bletchley Park staff to solve this crime; reveal the spy and retrieve the stolen decrypts!

In 1863, Professor Potch’s favourite author, Lewis Carroll, has been caught up in a horse and cart accident in Bucklebury market, and is now in hospital suffering from a head injury that has caused some funny goings-on, most dreadfully, memory loss! And the worst part – Lewis Carroll had just begun writing his masterpiece, Alice’s Adventures in Wonderland, which Professor Potch now fears will never be published!

It’s Tuesday 4th September 1666 and The Great Fire of London has been burning for two days. Order has begun to break down and chaos is threatening to erupt – fuelled by the rumours that the fire was started on purpose… Londoners are blaming every stranger that crosses their path. Is it another attack in the long running feud with the Catholics? A retaliation in the war with the Dutch? Or was it just an accident? Only one man knows the truth about how the fire started, and that man is Thomas Farriner, a baker from Pudding Lane, from whose bakery the first flames appeared on September 2nd… But with his house and, in fact, his entire street long destroyed, Farriner and his three children have fled to safety at the house of his brother David, on Mincing Lane. Meanwhile, a Frenchman by the name of Robert Hubert has been arrested on suspicion of starting the fire. If found guilty, he will hang, and although he doesn’t seem in his right mind, and his story doesn’t add up, the authorities want someone to blame and are ignoring their suspicions that he is innocent. In order to set things straight and stop London collapsing into paranoid anarchy, Thomas Farriner must be convinced to deliver a statement describing what really happened on the night of September 2nd through the door of the nearest church. But first, someone must brave the fiery streets and dastardly challenges in order to find him… The question then is, what will he decide to say? The fate of London awaits…
