Tommy Tevis and his friend, the big fat Black Mouse, formed a fantastic pair of detectives. Their office? A library of thousands of volumes! The cases they solved? Any mystery hidden in the pages of books! Then one day Nero Mouse left the city library, moved to the countryside with his new bride Rattìlia and the Investigalibri Agency closed forever.

Well, not forever. Far from his beloved books, Nero Mouse has fallen ill with nostalgia, and there is only one medicine that can cure him: go back to the library and reopen the Investigalibri Agency with Tommy, just like in the old days.

So, let's follow Nero and Tommy on their amazing new adventures. In this volume, three investigations not easy at all: a new client for the Agency... but maybe he is simply a short-sighted mouse, who got lost in the sewers and got the wrong office! Suspiria, the secret daughter of Nero Mouse: so freaky that she is terribly suspicious! And finally, writer's block. In other words: what happens when a great novelist, or supposed to be one, loses his inspiration and turns to two detectives to find it?
