a criminal call the bat roams around the mansion house of cornelia ( grayce hampton ) look for a secret room with hidden money . we have see that he have no problem in kill anyone that come in his way at the beginning of the film but we do not know his identity . a cast of character appear at the mansion and the story be a who dunnit mystery . so and who be the bat . the film start well but unfortunately and it go downhill when the action switch to the mansion house . this be largely due to the overbearingly dreadful maid lizzie ( maude eburne ) who play everything for humour and just never succeed . she be very irritating . of course and one irritating unfunny character isn not enough so we be introduce to 2 more . a butler or house keeper type who also play for humour and fails and a detective ( chance ward ) who be also very annoy and very unfunny . these 3 character be a big part of the reason why this film be rubbish . the other be the story which be dull and complicated and i find myself watch a totally confusing mess . the only good thing about the film be some of the camera shot and grace hampton who play her role well . they stick an epilogue on at the end of the film which be really tacky . this film be not good .
