The case file:
Here is how I solved the case:
The Scheme: all the colors used.
Evidence: Silver metal (stars); Numbers (silver 2), fabric ric rac, stitching.
Testimony: I made up my own 6-word memoir. : "Grandparents home where cousins become friends." The journalling on the back: "Stefan and Juan, you were born only two months apart. The two of you love playing together and love running, climbing and jumping. With the two of you it is just "go,go,go". I am sure that you will grow up to become best friends. xx Ouma."
