THE STORY
Neil Collins’s body is discovered in a local park in Mercia-upon-Tame. What brought a construction company owner here—and who had a reason to make sure he never left?
The investigation draws you into business rivalries, troubled histories and accounts that demand careful scrutiny. Several people have connections to Neil. A connection alone is not proof.
You have access to the Stanfordshire Police case files: scene records, forensic evidence, witness statements and interview recordings. Lay the accounts alongside the records and test what each one can actually establish.

GOOD TO KNOW
A few things to know before you take the case.
An online case-file investigation. You examine evidence in a fictional police system and decide what happened. There are no character scripts to act out.
Yes. Investigate on your own or gather around a screen with a partner or friends to discuss the evidence.
No. You can work through the investigation online. This is a digital case file, not a physical box.
A laptop or desktop gives documents, video and the evidence viewer more room. You play in your web browser.
Yes. Your investigation workspace saves progress to your account, so you can return to the evidence later.
Set aside around 120–240 minutes. Take your time: discussion and close reading are part of the investigation.

A Summer To Die For
Make room for a longer investigation. The answer is in the details.

Sorry but there is absolutely no way that the evidence available is going to lead people to the right person.
Their justification for who the killer is cannot be determined from what you are presented with.

I really enjoyed my time spent over the past few days working on this. The timeline of events was very well constructed so that all of the suspects seemed a hair’s breath away from ending up as being named murderer by me at different moments during the case, though I was able to settle on a final candidate, who did turn out to be the killer.
I was impressed with the level and quality of detail and work put into this case.
I’m planning on getting the other case available soon and will be looking forward to your future cases.
