Helena Worthington

Helena, the only daughter of eminent lawyer Henry Worthington KC, is a London based friend of Pen. She joined the investigators when they went to see the strange paintings of Miles Shipley, and got involved in the resulting battle with his Lizardman "mother". She then joined their investigations of Edward Gavigan and the Penhew Foundation. Initially, Helena saw mythos investigation as yet another new diversion to relieve the habitual boredom of a Bright Young Thing, but all that changed when her brother Richard disappeared into Shipley's Masterpiece. She joined the investigators on their journeys to Cairo and Kenya, not only to keep Pen company, but to attempt to learn where Richard had vanished to, and how to get him back.

Helena did not find any information on retrieving Richard. But during her travels, she became attached to both her Thompson Submachine Gun and the wooden mask that Pierre found in Ju Ju house. But the frequent use of "Maskie" affected Helena and she developed an ability to throw objects using her mind.  

She also developed a desire to accumulate minions to help her build a tall stone tower , but the investigators were sure that this was only a passing phase...

Helena left the investigators in the Lost City under the Australian desert, after she met Kakakatak,  a member of the great race dragged forward through time by Dr Huston. She hoped that together, she and "Mr Kakatak" could find the means to rescue her brother Richard. 

Helena then spent a year occupying a Yithian body in the distant past, while her body in the present was occupied by  Helena MkII, She has recently reclaimed her own body, but it is currently unclear what effects this sojourn in the past will have on her.
