Retired engineer and widower Reginald lives alone in a nice apartment complex.

When he receives an unexpected visit from the president of the resident's association, he's suddenly asked to take over as building manager. The reason? The young lady that he will inherit the position from has recently been murdered.

Reginald accepts the position – and the keys – to begin his new responsibilities, and it's then that he discovers a shoebox full of diamonds.

Entangled in the mystery of the woman's death, and falling fast for her mother, Reginald digs for answers... but this plot goes deeper than even he could anticipate.
