Magic item ideas for my sad detective PC?

My next character is going to be a human Pugilist (Benjamin Huffman) using the Bloodhound Bruiser subclass

Basically, he is going to be a noir style detective, grizzled and hardened by the cruel world around him,but with a heart of gold that motivates him to continue to solve crimes.

Our DM is starting us at level 5, and has told us that if we write s good character backstory and create some custom NPCs to contribute to the world, he will give us one "significant" magic item and another "minor" magic item.

I'm very excited about this character, I'm going to write the backstory from the perspective of a series of investigator log entries, print it out in a file folder with suspect photographs, the works. His ultimate goal will be searching for his wife who mysteriously ghosted him, as well as tracking a killer he hasn't been able to catch yet

Any ideas for fun, thematic magic items that lean into the detective playstyle, or otherwise focus on unarmed punchy pugilist fun?
