THE CANTERBURY PUZZLES
of the green-eyed monster, and formed the opinion that Lord
Marksford was flirting with other ladies of his acquaintance.
Now, she has actually put one of Dovey's spies on to that
excellent husband of hers ; and the myrmidon has been shadowing
him about for a fortnight with a pocket camera. A few days ago
he came to Lady Marksford in great glee. He had snapshotted his
lordship while actually walking in the public streets with a lady who

What is the use of this at all ?' asked the jealous woman.
Well, it is evidence, your ladyship, that your husband was
walking with the lady. I know where she is staying, and in a few
days shall have found out all about her.'
But, you stupid man/ cried her ladyship, in tones of great con-
tempt, how can anyone swear that this is his lordship, when the
greater part of him, including his head and shoulders, is hidden from
sight ? And—and'—she scrutinised the photo carefully—' why, I
guess it is impossible from this photograph to say whether the gentle-
man is walking with the lady or going in the opposite direction !'
" Thereupon she dismissed the detective in high dudgeon. Dovey
has himself just returned from Paris, and got this account of the
incident from her ladyship. He wants to justify his man, if possible,
by showing that the photo does disclose which way the man is go-
ing. Here it is. See what you fellows can make of it."
Our illustration is a faithful drawing made from the original
photograph. It will be seen that a slight but sudden summer shower
is the real cause of the difficulty.
All agreed that Lady Marsford was right—that it is impossible
to determine whether the man is walking with the lady or not.
" Her ladyship is wrong," said Baynes, after everybody had made
a close scrutiny. " I find there is important evidence in the picture.
Look at it carefully."
" Of course," said Melville, " we can tell nothing from the frock-
coat. It may be the front or the tails. Blessed if I can say ! Then
he has his overcoat over his arm, but which way his arm goes it is
impossible to see.'
" How about the bend of the legs ? " asked Churton.
