The sixth book in Eva Gates Lighthouse Library Mystery series is again set on North Carolina's Outer Banks. This novel opens with work being done to shore up the historic library and a coordinating children’s construction zone where the young library guests can practice their digging skills and pretend to be part of the construction project. Lucy, the protagonist of this series is in the library when the construction foreman comes in to announce all the library staff needs to follow him outside. As it turns out, all the digging has uncovered a small tin box which contains a diary another sheet of nonsensical writing, and a map. Speculation abounds as to whether or not it is a treasure map or something else relating back to the “War Between the States”.
The library staff and uninvited members of historical society have crowded into the director’s office, all intent on examining the contents of the box. As soon as the director sees the document and the lack of any buried treasure, she announces the book will be locked until their rare documents specialist can examine it, as she is the only one who is trained in handling old documents without destroying them.
Later that night, Lucy discovers someone has broken into the lighthouse and one of the people who were in the office earlier in the day is dead, clearly murdered. Lucy vows this time she is not going to get involved in the search for the killer and is going to focus her efforts on trying to break the code that will reveal the message from the author of the boxes contents. As expected, circumstances and her natural inclination toward solving puzzles keeps pulling Lucy back into the investigation.
There are some regular secondary characters including Louise Jane, a local storyteller and sometimes Lucy rival for the library position, Conner, the mayor and Lucy’s boyfriend, Sam Watson, the chief investigator for the police department as well as the library director, the rare documents specialist, and some town residents who appear briefly, but help round out the reader’s knowledge of the community.
Throughout the book there are two mysteries, first is who is the murderer and second is what is the significance of the coded message found in the box. The two investigations intertwine nicely and help to pull the reader through the book at a steady pace. Both investigations reach a satisfying conclusion. There were both reasonable clues and some good red herrings that help keep the reader on their toes. After the mysteries are solved, there is a nice, short wrap-up that helps tie off any loose threads.
The book works well as a stand-alone, however if the reader plans on reading the series, there are some secondary storylines that build as the books develop and it might be more enjoyable to read the series from the beginning. This series is a good cozy series, with some interesting glimpses of life on the wild coast of the Outer Banks which also adds to the book itself. I recommend it to anyone who enjoys cozy mysteries and who might enjoy a virtual trip to the coast.
