Gigi Chihuahua Mystery Books in Order

The Gigi Chihuahua Mystery books are light, offbeat mysteries with a paranormal wrapper and a strong comic streak. What really ties them together is the staff of Tripping Magazine, a small publication based in Boulder that chases haunted destinations, creepy folklore, and stories strange enough to pull readers in. That gives the series its central joke and its main source of tension, because the team is always walking into cases that look supernatural from the outside and human from the inside.

They are less ghost hunters than curious meddlers with a deadline.

At the center are Angus MacGregor, the editor who wants a great story, Michael Abernathy, the more skeptical writer, and Suki Oota, the photographer who helps ground the investigation even when events start to look ridiculous. Their personalities rub against each other in useful ways. One person leans toward belief, another toward debunking, and the result is a steady back and forth that keeps the books lively even before the mystery fully clicks into place.

Chihuahua of the Baskervilles sets the pattern. The team heads to Manitou Springs, Colorado, after Charlotte Baskerville reports seeing the glowing ghost of her dead Chihuahua. The town's tourist appeal, local legends, and coffin-race atmosphere give the story a playful backdrop, but the real question is who around Charlotte wants something badly enough to stage scares, push her off balance, or worse. The spooky setup is fun. The motives underneath it are not.

The Portrait of Doreene Gray takes the same mix of humor and unease to Port Townsend, Washington. There the Tripping crew investigates an aging portrait, a woman who does not seem to age with it, and a wealthy household full of nerves, history, and resentment. This book leans a little more Gothic, with a mansion, locked rooms, and old secrets, while still keeping the banter and off-kilter energy that define the series. Gigi herself matters more here, as a companion animal and comic presence rather than a detective dog.

Across the series, the author uses ghost stories, odd festivals, and eccentric tourist towns as bait, then builds the actual mystery around greed, jealousy, family strain, status, and fear. The Chihuahuas are memorable, but they are not a gimmick pasted on top of an ordinary cozy. They help set the tone: a little absurd, affectionate toward human weakness, and willing to let something tiny steal the scene. If you want mysteries that flirt with the paranormal, enjoy regional color, and solve their puzzles through conversation, observation, and personality clashes, this series is a good fit.
