Novel Suspects is a website and newsletter from Hachette Book Group. It covers crime fiction and horror, including true crime. They include book lists, obviously with Hachette titles. However, you can borrow the idea and use the books in your collection.
"Cannibalistic Cravings: 5 Gourmet Thrillers with ‘Unique’ Taste" is a recent list that could make a creative display. In addition to crime fiction, horror, and true crime, a display like this could include cookbooks as well. There are a number of lists below with books that you can use.
The same display could be done with cozy mysteries with food themes. Cozy-Mystery has lists of culinary mysteries.
I love the titles that Book Riot used - Fed Up With People and On the Menu. They are both clever and could be borrowed for your display with credit give to Book Riot.
