Detective Axe, the protagonist of this book, is a famous detective in heping town! Detective Axe is actually a mathematician, and detective is just his hobby. He always uses mathematical knowledge to solve cases, and there is no case that he can't solve.

Detective Axe is good because he can solve crimes with mathematics. On one occasion, General Moustache's rocket was stolen by others, and an inspector's axe was invited. Detective Axe carefully observed that there was a footprint not far away, one deep and one shallow, so Detective Axe figured out that the suspect was lame, and then watched the time and video of the crime scene. Although the video is vague, it can't be hidden from Detective Axe. He calculated the speed of the suspect and easily caught the suspect in the "Happiness Hotel" next to him.

Detective axe's weapon is also very interesting! His weapon is tobacco in his pipe. There are many kinds of tobacco in his weapon pipe, some are narcotic, some are ordinary .........................................................................................................................................................., and the pipe is also very useful. This pipe is very strong. Detective Axe hit a lot of things with the pipe, but the pipe was still intact. The pipe was even hit by a bullet, and nothing happened. How amazing!

This book is very interesting and I want to share it with you.
