If so, she must have gone there to meet some one. Now we know from Dr. Sheppard
that some one from outside _did_ come to the house that night—the stranger whom
he met just by the gate. At a first glance it would seem that our problem was
solved, and that the stranger went to the summer-house to meet Ursula Bourne. It
was fairly certain that he _did_ go to the summer-house because of the goose
quill. That suggested at once to my mind a taker of drugs—and one who had
acquired the habit on the other side of the Atlantic where sniffing ‘snow’ is
more common than in this country. The man whom Dr. Sheppard met had an American
accent, which fitted in with that supposition.
“But I was held up by one point. _The times did not fit._ Ursula Bourne could
certainly not have gone to the summer-house before nine-thirty, whereas the man
must have got there by a few minutes past nine. I could, of course, assume that
he waited there for half an hour. The only alternative supposition was that
there had been two separate meetings in the summer-house that night. _Eh bien_,
as soon as I went into that alternative I found several significant facts. I
discovered that Miss Russell, the housekeeper, had visited Dr. Sheppard that
morning, and had displayed a good deal of interest in cures for victims of the
drug habit. Taking that in conjunction with the goose quill, I assumed that the
man in question came to Fernly to meet the housekeeper, and not Ursula Bourne.
Who, then, did Ursula Bourne come to the rendezvous to meet? I was not long in
doubt. First I found a ring—a wedding ring—with ‘From R.’ and a date inside it.
Then I learnt that Ralph Paton had been seen coming up the path which led to the
summer-house at twenty-five minutes past nine, and I also heard of a certain
conversation which had taken place in the wood near the village that very
