The key arrived in a coffin-shaped box with no return address; the body came later. 

When Luci receives an old key and a ticket to the past, she gets more than she bargained for by way of a corpse, a mysterious family connection, and a nursing home patient with early-stage dementia. 

As the detective helps her piece together each cryptic clue from tools to gold to peculiar photos, Luci realizes trouble comes to those who dig too deep when death, danger and buried treasure don't make for polite bedfellows. 

If she’s going to stay alive to find out why her parrot, Simon, hates going into the basement because of what secret the key unlocks, Luci must rely on an unlikely team - her wits and a woman who called her by her dead grandmother’s name.

She needs to outmaneuver someone with murder on their mind now that the body’s been found. 

After all, behind every door is a secret, and this one could kill her AND her parrot.
