Maurice Oyle is the manager of Grynde, an American meat producing company. (In the original French, his name is Tom Awake; in the redrawn French edition his name is Tom Hawake. Tom manages Slift & Co., a play on Swift & Co.)
Secretly, Maurice is in contact with the Director of Kidnap Inc, Bugsy Kidnap. When the director escapes from Tintin by falling through a trapdoor, he calls Maurice and tells him to get rid of Tintin.
The next day, Tintin receives a letter from Grynde telling them to come and visit their factory. Maurice takes him upstairs to where the making is done, Maurice activates a switch making the fence fall down. He then realises that there is a strike and that Tintin has survived. He goes over to his boss's house and the boss knocks him out. He is last seen being taking away to prison.
