2. What are the clues found at the murder site? Why does Holmes think that the clues found at the murder site are not strong evidence?

From the text:

"We found three or four grooms and idlers standing in the drive inspecting a bicycle which had been drawn out from a clump of evergreens in which it had been concealed. It was a well used RudgeWhitworth, splashed as from a considerable journey. There was a saddlebag with spanner and oilcan, but no clue as to the owner.

“It would be a grand help to the police,” said the inspector, “if these things were numbered and registered. But we must be thankful for what we’ve got. If we can’t find where he went to, at least we are likely to get where he came from. But what in the name of all that is wonderful made the fellow leave it behind?"
