this be a rather aimless mystery and with an implausible murder and an utterly impossible solution and require the witness to the murder to be death dumb and blind and and the corpse of the murder to be light a a feather . but that not especially unusual in mystery of the era . the problem be that this one be and by it story and stuck on a limited number of set and and the dialog be not enough to sustain interest over the rather brief run time . performance be fine no good than one would expect on par with an average episode of murder she write . it really not worth sit through this one to get to the solution . ( nor be it worth search out the book which be just a implausible and dull ) if you really like s van dine and and be determine to stick it out and there be one virtue the component of the murder plot that do not relate to the dragon and the swimming pool be neatly do .
