* Bill Cunningham: An important member (holding the rank of inspector) of an unspecified, quite
  possibly fictional secret service force (possibly based upon the British Secret Intelligence
  Service). His most prominent bodily feature is his half-bald head. He meets the children upon
  their very first adventure and makes regular appearances in the series from that point on. Mostly
  the children get tangled up in adventures which are connected with Bill's work at the time and end
  up solving them for him.
  Following the events in The Ship of Adventure, Bill marries Mrs Mannering and adopts all the
  children as his own. Upon first encountering the children, he used the alias "Bill Smugs" - a name
  which appeared again in The Mountain of Adventure.
