“How was she dressed?”
“In a fur motor-coat—civet fur.”
The man of culture spoke in those two words, “civet fur”; and Dunbar nodded quickly, his eyes ablaze at the importance of the evidence.
“Was she alone?”
“She was.”
“What fare did she pay you?”
“The meter only registered eightpence, but she gave me half-a-crown.”
“Did she appear to be ill?”
“Very ill. She wore no hat, and I supposed her to be in evening dress. She almost fell as she got out of the cab, but managed to get into the hall of Palace Mansions quickly enough, looking behind her all the time.”
Inspector Dunbar shot out the hypnotic finger again.
