We

must　leave　that　question　to　the　future。 Now　we　shall　turn　to　the

Cadogan　Wests。〃

A　small　but　well…kept　house　in　the　outskirts　of　the　town

sheltered　the　bereaved　mother。 The　old　lady　was　too　dazed　with

grief　to　be　of　any　use　to　us；　but　at　her　side　was　a　white…faced

young　lady；　who　introduced　herself　as　Miss　Violet　Westbury；　the

fiancee　of　the　dead　man；　and　the　last　to　see　him　upon　that　fatal

night。

〃I　cannot　explain　it；　Mr。　Holmes；〃　she　said。 〃I　have　not　shut　an
