The invisibles are a 5 person cell fighting authority using violence time travel, and various other chemicals and meditation highs. Pure fantasy reading, well perhaps not.
The bus stop for the bus I take to work overlooks a canel. One day there was yellow sign on the grass by the canal warning people not to walk there, because a company was spraying for Japanese wank weed. On the other side of the canal men in huge black gas masks were marching up and down with huge yellow casks on their backs. People mostly ignored the signs, when their dogs need to shit, no deadly weed is going to stop them.
At work more workman walk outside my office on the concrete balcony wearing huge shiny gas masks and muttering to each other in some strange topologically twisted language. The building manager said they were removin asbestos. But that doesn't seem likely for a building built in the 1960s.
One day I walked out to the bus stop. There was a cracked car, its windows were all shattered. White silky fluid was sprayed all over the car. When I came home at night, the car was gone. Perhaps someone was trying to reach me, to give me some kind of message, but was stopped. Too many strange things are happening close to the canal.
