«My name is MINERVA, MINERVA WATSON. I am a direct descendant of the greatest detective of all time and, I have got into trouble. Into a big one.»​​​​​​​

Thus begins the first of the four adventures written by Carlos Salem for Edebé publishing house.

The Amazing Case of the Wrong Shadows, the Unusual Case of the Phantom that Was Not a Real One, the Wasting Time Machine and the Mountains Thieves are the four cases Minerva will have to face.
