Stick of Doublemint

On a warm San Francisco night, an innocent young woman is gunned down during a gang-related drive-by shooting.

Then those involved in the shooting start turning up dead, with a stick of Doublemint gum in hand. What does it mean, and who's responsible?
A new detective is assigned to the case, and he quickly realizes he's going to need help to solve it, so turns to old friends, Katy Green and Johnny Cato, now part of a successful private investigation firm!
So begins a race against the clock to stop further murders and to discover the perpetrator. Can the investigating duo, dubbed by newspapers as "Green Hornet and Cato" solve this latest case of the vigilante killings, or will the culprit continue to bloody the city?
