Insignia oficial de Casey Crane — C.C. Investigates.

A note from the detective

Meet C.C., your partner in curiosity

Casey Crane has a soft spot for overlooked details, dry observations, and cases that fit into real life. C.C. brings the file. You bring the deduction.

Cozy Crime Files makes room for the pleasure of noticing: investigations to solve with the information in front of you, away from the endless scroll.

“The kettle can wait. That detail cannot.”

— Detective C.C.

A few things before you investigate

1
Will anything arrive in the post?

No. These are downloadable PDFs to print at home. There is no physical shipment.

2
Are both languages included?

No. Choose the English or Spanish edition. Each purchase includes A4 and US Letter files in the selected language only.

3
Which print size should I choose?

Choose the PDF that matches your paper: A4 or US Letter. Both sizes are included in each edition; you only need to print one.

4
How long does a case take? Is there a time limit?

The times we show (5 minutes, 5–30 minutes…) are only an estimate. Everyone reads and reasons at their own pace, so it will vary from person to person.

They're not a countdown and there's no time limit: take all the time you need. The best case is the one you enjoy, not the one you finish fastest.

5
Do I need an app or internet research?

You need internet access to download your file. The investigations themselves are designed to be solved from the information provided.

6
What is the difference between Volume 1 and Cozy Nights?

Volume 1 brings together 12 cases of around 5–30 minutes each and is available now. Cozy Nights offers longer cases to play at your own pace and is coming November 11.
