Concealed: to keep from sight (adjective)
This is the meaning of the word concealed according to Dictionary.com. I saw this word when I was reading A Jury Of Her Peers again the day after black friday. I saw it in the sentence that said “Mrs. Hale’s hand was on the sewing basket in which the box was concealed. She was hiding the evidence from the police who was investigating. She was making sure the police didn’t see the box which could’ve been used as evidence.
