The pretty private eyes from the Triple Threat Investigation Agency—JJ, Rey, and Linda—have a new case, thanks to a serial killer who has taken a serious interest in them. The GrimReaperPeeper has challenged them to “play the game”, by his rules.

Rules are made to be broken, however ... or, at the very least, altered.

Baffled but resolute, the trio attempt to determine who he might be. Not an easy feat, given the lack of constructive evidence and cast of oddball characters. As they endeavor to stop the killer, they must solve a couple of other cases: verifying whether a hubby has a roving eye and ascertaining who is stalking a young, beautiful woman. As clues are uncovered, so are coincidences. Could it be that these two cases somehow intertwine? Might there even be a connection to the serial killings?

Who will prove the ultimate winner in this deadly game of taunts and perplexities: the clever and cunning GrimReaperPeeper, or the persevering and persistent P.I.s?

The fifth novel in the Triple Threat Mysteries by Tyler Colins, HA-HA-HA-HA is a compelling cozy mystery with grit … and plenty of laughs, and twists and turns.
