There are only two detectives to protect the city from evil in the late night, but one of them is a wizard. There are many shops on a special street that one evil man wants to have for his own, but one of the shops belongs to a witch. Most important of all, to make the triad complete with the wizard and the witch, a fat black cat with reflective green eyes could save them all.

Allegra thinks life should be quiet, since she is a talented witch with a familiar, a beautiful large fat black cat with reflective green eyes who has the need to be territorial. Unfortunately, she runs a curio shop on a small street that an evil man has decided to buy so he can level the shops and build a tribute to himself.

To help fight evil, there are two interesting detectives of the night. One is a large powerful wizard who wants to invade Allegra’s bedroom. The other is a brilliant but clumsy human with talent in computers and puzzles.
