Take a look at the hints below for guidance.
Hint 1
To solve the case, you’ll need to eavesdrop on several telephone conversations that happened before and after the murder. Accessing a particular phone call requires the date and time the call occurred, as well as the two phone Mains the participants were calling from.
Hint 2
Arthur mentioned the location of a local telephone exchange in his intro letter, can you find it on the map?
Hint 3
Is there anything else on the map nearby that might indicate that there’s more to this location than meets the eye?
Hint 4
The switchboard can be found here: www.14tiltonlane.com.
Hint 5
Mains are always preceded by “02–”. For example, the information for a phone call might look like this: August 4th, 4:00pm, Mains 0202 and 0203.
Hint 6
The date, time, and each Main # for a given phone call may all be located in different pieces of evidence. Cross-references names or locations that appear in multiple pieces of evidence and look for a mention of a Main #.
