been traced without the slightest difficulty. He dined at the Cafe Royal
alone, promenaded afterwards at the Alhambra, and drove on about
supper-time to the Continental. He left there at 12.30 with a couple of
ladies whom he appeared to know fairly well, called at their flat for a
drink, and sent one out to his cabby--rather unusual forethought for such
a bounder. When he reappeared and directed the man to drive him to
Cavendish Mansions, Battersea, the driver tried to excuse himself. Both
he and his horse were dead tired, he said. Barnes, however, insisted upon
keeping him, and off they went. At Cavendish Mansions, Barnes alighted
and offered the man a sovereign. Naturally enough the fellow could not
change it, and Barnes went in to get some silver from his rooms,
promising to return in a minute or two. The cabby descended and walked to
the corner of the street to see if he could beg a match for his pipe from
any passer-by. He may have been away for perhaps five minutes, certainly
no more, during which time he stood with his back to the Mansions. Seeing
no one about, he returned to his cab, ascended to his seat, naturally
without looking inside, and fell fast asleep. The next thing he remembers
is being awakened by Wrayson here! So much for the cabby."

"What a fine criminal judge was lost to the country, Colonel, when you
chose the army for a career," Mason remarked, turning round to order some
coffee. "Such coherence--such an eye for detail. Pass the matches,
Wrayson. Thanks, old chap!"

The Colonel smiled placidly.

"I am afraid," he said, "that I should never have had the heart to
sentence anybody to anything, but I must admit that things of this sort
do interest me. I love to weigh them up and theorize. The more
melodramatic they are the better."
