[Harry Potter] Why did Barry Crouch Jr. (fake mad eye) bother with the triwizard tournament?

If he wanted to trick Harry to Voldemort, couldn’t he have just invited Harry to his office and said “hand me that pencil”, with the pencil being a port key to the graveyard?

Voldemort didn’t want anyone but his followers to know he had returned at this point. So they needed to teleport Harry to Voldemort, restore Voldemort, kill Harry, and then teleport Harry back to where he was so that no one would ever know Harry had vanished and there would be some reasonable explanation for Harry’s death outside of being murdered by Voldemort.

The tournament allowed them to put Harry in a potentially lethal situation out of prying eyes so that Hogwarts and the Wizarding World would think he died in the tournament, which is something that is known to happen to tournament participants in order to camouflage Voldemort’s return.
