Category 3- Weapons
#4-Wrench – Read a book with a wrench on the cover or a book whose cover shows anything that might be purchased in a hardware store (i.e. hammer, saw, nails, paint).

Extremely challenging to find a book with needed items on the cover. After extension search found book with a key & lock on the cover, which I hope is acceptable since keys/locks (door hardware) can be purchased in a hardware store.

Book Title: A House Divided by Judith Cutler
(a Harriet & Matthew Rowsley Victorian Mystery)
