I am looking at the API documentation and I am not seeing how Leads and Tasks are related.  I know that they are because on SF.com I can associate Tasks with Leads.  I want to query the web service api and retrieve all new tasks created in the past month and the Leads they are associated with.  All I am seeing is Task.AccountId and that doesn't seem to contain anything for Tasks that are associated with Leads.

Thanks
