to　sell　the　secret；　intending；　no　doubt；　to　have　the　plans

themselves　back　in　the　safe　next　morning　before　they　were　missed。

While　in　London　on　this　treasonable　mission　he　met　his　end。〃

〃We　will　suppose　that　he　was　travelling　back　to　Woolwich　when　he

determined　to　convey　these　papers　to　London。 He　would　naturally

have　made　an　appointment　with　the　foreign　agent　and　kept　his

theatre；　escorted　his　fiancee　halfway　there；　and　then　suddenly
