Oahu, Hawaii

Does this book contain any explicit language or adult scenes?

There are two swear words (used by a gruff/smug cop).  No sex scenes to speak of, just a shower scene, which is more comedic than anything (and nothing happens).

If a series, can it be a standalone?

It probably could.  (The first book was meant to be a standalone, with the three women donning amateur sleuthing caps and solving a crazy slew of murders at a haunted mansion, but they wanted to continue and, thus, “wrote” the stories.  😉)

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.

About Tyler Colins

Tyler Colins has several years of experience as a fiction writer and blogger.  She has also edited and proofread books, manuals/documents, and film/television scripts.  Additionally, she considers herself a “fastidious organizer” of facts, files, and fripperies.

Between the nine-to-five (which is more like 4:30 a.m. to 6:30 p.m.), editing, and mom-care, she’s working on the sixth book in the Triple Threat Investigation Agency series: Disco’s Dead and So is Mo-Mo.

As time streams past, like a winding burbling brook, dreams and plans change, but her love of mysteries never does.
