Hush-Hush — Elizabeth Spann Craig

It's hard keeping secrets in small towns. At first, librarian Ann Beckett is delighted her director hired another full-time staff member. The Whitby Library is a busy place and another librarian should make life much easier there. Instead, she soon discovers that the new hire, Ellie, seems to be bent on creating issues instead of solving them. When she's found dead at the library, no one is as shocked as they might have been. With time running out and a desperate killer on the loose, Ann starts uncovering all the secrets Ellie was trying to keep hush-hush.
