She
ordered me to keep him in sight; and as I drove off I heard her calling
from the window of my cab to another lady who seemed to be following
her. I was unable to see this other lady, but my fare addressed her as
'Denise.' I followed the first cab to Whitechapel Station; and as I
saw it stop there, I swung into Mount Street. The lady gave me
half-a-sovereign, and told me that she proposed to follow the man on
foot. She asked me if I could manage to keep her in sight, without
letting my cab be seen by the man she was following. I said I would
try, and I crept along at some distance behind her, going as slowly as

"Have you anything to add to that?" said Dunbar, fixing his tawny eyes
upon the cabman.

"Nothing at all," replied the man--a very spruce and intelligent
specimen of his class and one who, although he had moved with the times,
yet retained a slightly horsey appearance, which indicated that he had
not always been a mechanical Jehu.

"It is quite satisfactory as far as it goes," muttered Dunbar. "I'll get
you to sign it now and we need not detain you any longer."

"There is not the slightest doubt," said Dr. Cumberly, stepping forward
and speaking in an unusually harsh voice, "that Helen endeavored to
