Jem corroborated Bet. Grimethorpe had returned at about 1:50 a.m. on October 14th, drunk, and plastered with mud. He had muttered something about having run up against a man called Watson.

The ostler was next interrogated. He did not think that anybody could get a horse and trap out of the stable at night without his knowing it. He knew Watson. He was a carrier by trade, and lived in Windon Street. Lord Peter rewarded his informant suitably, and set out for Windon Street.

But the recital of his quest would be tedious. At a quarter past noon he joined Bunter at the Meribah memorial.

"Any luck?"

"I have secured certain information, my lord, which I have duly noted. Total expenditure on beer for self and witnesses 7s. 2d., my lord."

Lord Peter paid the 7s. 2d. without a word, and they adjourned to the "Rose and Crown." Being accommodated in a private parlor, and having ordered lunch, they proceeded to draw up the following schedule:
