Jon and Mr. Shadow

Jon is a young private detective and Mr. Shadow, a talking cat, is his assistant. The two were hired by you because you noticed strange happenings in your neighborhood. Since you were born, you have lived in the old house of your grandmother, who died six months ago, at the end of the street, and for the past three months you have always seen people wandering through the streets at night and seeming to be looking for something. You also hear creepy whispers in the early hours of the morning and before darkness falls the old boards creak particularly loudly.
