the lodger be a others have already say hitchcock first suspense movie . though i have not see movie from him before this picture . this contain spoiler . the plot outline be a follow while 7 girl with curly blond hair have be kill all on tuesday night . a suspicious look man rent a room in an apartment from a family . the family represent a mother and father and a daughter with curly blond a hair ( daisy ) . the lover of the daughter be a policeman . the daughter of the house be get attract to the lodger . when mother notice that the lodger leave on a tuesday night the parent try to stop the affair . daisy doesn not listen to the advise and leave with the lodger on a tuesday night . when the policeman suspect the lodger of the killing he search his room and find a gun and the map with the murder on it and a picture of a girl with curly blonde hair . he arrest but manages to escape and daisy follow him . he then tell daisy the real story behind it . soon the whole neighborhood be follow the handcuffed lodger . the policeman then hear the real murderer be catch red hand and the real story come out . only now the lodger have to be save from the crowd who still think that he do it . it really be a wonderful piece of silent cinema . and already a perfect example of the cleverness of hitchcock . he already use so many technique for build up the suspense . he also manage to let the image speak . there be so much to see in the mise en scene and the effect and the editing . the story be very easy to follow and everything be make very clear when there be no sound . sound be really important and make the story a lot easy to follow . a i have see both hitchcock silent and talkie version of blackmail and you can really see the difference . the acting have to be really expressive in a silent flic . so everything becomes clear about what they think . in talkie such thing can be tell with sound . in an early comment i read that the lodger be a bit overact . i do not think that he overact to the standard that be use in those day . he have to act that way to make clear his mental state . other example can be find in the mise en scene . for example the fog when he first enter and the flickering light a if something be go to happen etc . this really be a clever and intelligent movie make by the master of suspense . i do not expect it to be that good when i be go to see it but it really blow me away that he already be so inventing in build up suspense . a must see .
