Tool to Peek into WCF SOAP message

I know there is a tool that enables me to see what actually gets sent/received in my WCF application, that is it let's me see the actual SOAP messages being passed down the wire. The problem is I don't remember what that tool was called, and my Google skills are not of much help either. Anyone?
