Chapter 4

The image resembles the display of a mobile messaging app. The image comprises a sequence of dates (in white text on a black background) and with a message (in white text on a purple background) below each date. The dates and messages are as follows: 10/04/22 Will you be able to do this? I'll send you strange messages to crack! 05/22/23 Theres something out of equilibrium here 05/06/22 I wonder if you are able to solve this? 06/08/22 Hi I will send you everything you need to know 31/09/22 Wow I am starting to give clues to aid solving this now! 05/10/22 Hi Are you thinking about all the messages Ive sent? 24/10/22 This message will be really necessary to solving this! 23/12/24 Although it might seem a strange collection of messages - it really isn’t! 05/01/23 Hmmm Could this be almost it? The penultimate message? 29/01/23 Hi I regret to say that this indeed will be the last message. But I think I've said enough At the bottom of the display is a grey box containing the text 'Type a message...'.

The image above contains a hidden message that when deciphered should be a question. Please enter the answer to that question in the box below.
