It must be that Mr Verloc was susceptible to these fascinations.

Mr Verloc was an intermittent patron.

He came and went without any very apparent reason.
He generally arrived in London (like the influenza) from the Continent, only he arrived unheralded by the Press; and his visitations set in with great severity.

He breakfasted in bed, and remained wallowing there with an air of quiet enjoyment till noon every day--and sometimes even to a later hour.

But when he went out he seemed to experience a great difficulty in finding his way back to his temporary home in the Belgravian square.
