Chester Thompson is a hired thug. In order to keep the lid
on the Mick Barnard conspiracy, Chester was pushed on the
band by their evil manager Tony
Smith, who has direct ties to the Phillips crime family.
The story was that Chester was a drummer. This forced Phil
Collins into the position of lead singer (up until that point,
after Gabriel's forced departure, Genesis had planned to become
an instrumental band). Meanwhile, Chester was there in the
background, keeping an eye on the members of the band and
leaving them threatening messages if they seemed ready to
spill secrets about Mick. It is known that Chester was slowly
poisoning Phil Collins, causing him to lose his hair, and
that he would put bugs in Gabriel's Slipperman costume.
