Oops, this was crap, of course. :) It should have been:

    construct { ?stmt ?p ?o . }
    where {
        $stmt a rdf:Statement ; 
              rdf:subject me:Alice ;
              rdf:predicate foaf:knows ; 
              rdf:object he:bob .
        ?stmt ?p ?o .
    }

Sorry!

Cheers,
Michael
