One Loved a Soldier: Another, a Sailor, a Third, a Marine: Seventh in the Zuma Mystery Series

After a white female and black male couple are found murdered in Santa Monica and a series of robberies has been committed by an interracial gang, Captain Joe Zuma seeks a possible connection.

The infiltration of the gang and their efforts to rob stores and recruit further gang member and their holding the police infiltrator hostage leads to a set of negotiated demands between the gang and the police department.

The gang continues to recruit and plan robberies and three of the recruits are caught by the police.

Upon their release on bail all three are murdered by older gang members.

When the parents of the couple that were murdered are also murdered Zuma has 11 deaths that he must account for with the black and brown communities of color protesting the lack of arrests.

A homeless person who witnessed the shootings provides Zuma with his first clue which leads him to three white women who are sisters, and who've been involved with nefarious criminal activity.

Their efforts to cover for each other are broken by a brilliant ploy by Zuma.
