She removed an amulet upon a gold chain from about her neck and thrust
it into Stuart's hand.

"It seems to you silly, but Chunda Lal is of the East; and he has
promised. Oh! be quick! I am afraid. I tell you something. Fo-Hi
does not know, but the police Inspector and many men search the
river bank for the house! I see them from a window----"

"What!" cried Stuart--"Dunbar is here!"

_"Ssh! ssh!"_ Miska clutched him wildly. _"He_ is not far away. You
will go and bring him here. No! for me do not fear. I put the keys

She slipped from his arms, crossed and reopened the lacquered door,

the cowled garment and was now arrayed in a rich mandarin robe.
Through the grotesque green veil which obscured his features the
brilliant eyes shone catlike.

"So," he said softly, "you speed the parting guest. And did I not
hear the sound of a chaste salute?"

Miska watched him, wild-eyed.

"And he knows," continued the metallic voice, "'how to deal with
Chunda Lal'? But it may be that Chunda Lal will know how to deal with
_him!_ I had suspected that Dr. Keppel Stuart entertained an
unprofessional interest in his charming patient. Your failure to

was in order that some linger
