Subject: The mechanism for the decomposition of H2O2 with iron(III) as the catalyst?

When a solution of iron(III) ions is added to hydrogen peroxide, it's 
colour changes from pale orange/yellow to brown, and the decomposition 
reaction proceeds as normal.  Over the course of the reaction the brown 
colour changes back to yellow/orange, which may suggest that a complex 
has initially been formed, which then breaks down to give the products.  
What is the mechanism for this reaction - is it as conjectured above?
