`` When did you hear that the Motor Pirate was at work again ? '' `` At St. Albans . I called at the police office on my way here . He was seen about ten o'clock this side of Peterborough and going north . '' `` It will be rather a sell if Mannering is at home , '' I remarked . `` He will not be at home , '' replied Forrest with conviction . THE night was moonless , but there was that soft diffused light in the air invariable in June , except on the cloudiest of evenings .
