Sheila Connolly - Museum Mysteries (#1-5 inc 2.5)

Fundraising the Dead (Museum #1)
At The Society for the Preservation of Pennsylvania Antiques, fundraiser Eleanor "Nell" Pratt solicits donations-and sometimes solves crimes. When a collection of George Washington's letters is lost on the same day that an archivist is found dead, it seems strange that the Society president isn't pushing for an investigation. Nell goes digging herself, and soon uncovers a long, rich history of crime.

Let's Play Dead (Museum #2)
The new exhibit at the Philadelphia children's museum, Let's Play, isn't meant to be shocking-but when one of the installers is zapped with a fatal electrical charge, it's up to Nell to put her detective skills on display.

Dead Letters (Museum #2.5)
Nell Pratt’s search into a family’s history may bring more than just dark secrets to light. Nell Pratt, President of the Pennsylvania Antiquarian Society, is intrigued when Arthur Logan, elderly scion of an old Philadelphia family, approaches her to search the Society’s archives for information on the Logan family’s history. What he desires most, it turns out, is her discretion—but as Nell begins sifting through documents and letters, a series of unsettling occurrences lead her to wonder if she’s not the only one out there looking for a Logan family secret.

Fire Engine Dead (Museum #3)
When the entire collection of the Fireman's Museum ironically goes up in flames, Nell Pratt discovers one of the charred pictures isn't the one that was originally exhibited. But getting to the bottom of the mystery is bound to get Nell burned.

Monument to the Dead (Museum #4)
When Nell reads the obituary of a former board member, Adeline Harrison, she makes a mental note to send flowers and doesn’t think twice about it—until FBI agent James Morrison shares his suspicions about the nature of Adeline’s death. It turns out that a number of other members of the local cultural community have died in the last few months, under similar circumstances. Soon Nell uncovers what seems to be a plot to rid Philadelphia of harmless, elderly philanthropists—but why? If she can figure out the killer’s motive, she has a chance of stopping the misanthropic murderer before another do-gooder is done in

Razing the Dead (Museum #5)
Once again Nell Pratt has to dig into the past to solve a murder in the present.

Between the challenges of her position as president of the Pennsylvania Antiquarian Society in Philadelphia and of taking her relationship with FBI agent James Morrison to the next level, Nell Pratt has got her hands full. Nevertheless, when a powerful developer approaches the Society to make sure the old dairy farm he wants to level is not hiding any archaeological or historical surprises that could derail the project he’s planning, Nell decides to make time to personally accompany him to the proposed site.

But when they get to the property, they stumble upon a startling discovery—a body floating facedown in a pond. The dead man turns out to be an amateur history enthusiast, who may have uncovered secrets about the farm that got him killed. Now it’s up to Nell and James to get to the bottom of things before there are more deadly developments.
