Hugo and Albert multiplied their efforts.
'There's a cab driven up,' Simon informed them from the window. 'A man's got out. Now he's gone down the area steps. They're carrying something up, something big. Oh! look here, I must help you.'
And Simon ran to the door. Before the triple assault it fell at last, and the three tumbled pell-mell downstairs into the hall. The front-door was open.
A cab was just driving away. It drove rapidly, very rapidly.
'After it!' Hugo commanded.
The hunt was up.
Two minutes afterwards another cab drove up to the door.
Ravengar and another man emerged from the area holding between them the form of a woman. They got leisurely into the cab with the woman and departed.
