dangerous mania, and when,
as you come in through the garden to the house, the heiress
and her landlady and two of the gentlemen boarders join hands
and dance round you in a ring, calling out, "It's all right! it's
all right!" you are apt to be flustered and even displeased.
Dr. Warner was a placid but hardly a placable person.
The two things are by no means the same; and even when Moon explained
to him that he, Warner, with his high hat and tall, solid figure,
was just such a classic figure as OUGHT to be danced round
by a ring of laughing maidens on some old golden Greek seashore--
even then he seemed to miss the point of the general rejoicing.

"Inglewood!" cried Dr. Warner, fixing his former disciple with a stare,
"are you mad?"

Arthur flushed to the roots of his brown hair, but he answered,
easily and quietly enough, "Not now. The truth is, Warner, I've just
made a rather important medical discovery--quite in your line."

"What do you mean?" asked the great doctor stiffly--"what discovery?"

"Yes; sanity has broken out, and is spreading," said Michael,

and he may marry any one he likes--except me."

"I should suggest Mrs. Duke," said Michael.

The gravity of Dr. Warner's face increased. He took a slip
of pink paper from his waistcoat pocket, with his pale
blue eyes quietly fixed on Rosamund's face all the time.
He spoke with a not inexcusable frigidity.

"Really, Miss Hunt," he said, "you are not yet very reassuring.
You sent me this wire only half an hour ago: `Come at once,
if possible, with another doctor. Man--Innocent Smith--gone mad

I went round at once to a distinguished colleague of mine, a doctor
who is also a private detective and a
