The final round of a contest had one knight (always tells the truth), one liar (always tells lies) and three knaves (alternate between truth and lies). The knight placed first and the liar placed fifth. Afterwards, each of the five contestants made two comments:

Alex: Bert wasn't first. Carl finished lower than Dave.

Bert: I was second. Alex finished lower than Eddy.

Carl: Alex finished higher off than Dave. Bert was fourth.

Dave: Eddy was second. Carl wasn't last.

Eddy: Bert wasn't first. I was third.

In what order did the contestants finish?
