Lt. Columbo:  Finally got some hard evidence ! What is that , Doctor ? I 'll be a son of a gun . A calibration converter . Do you have the key to that case ? Looks like a _ 0.22 _ . Fit nicely into a 0.45 automatic . That 's why the barrel and chambers were clean when ballistics checked out the gun . That 's a lovely touch . A converter . I never figured on a converter . And one hidden in a lamp . Doc , I woulda sworn you had a gun hidden in here - and I was trying to smoke you out - but I never figured on this .
Dr. Bart Keppel: A subliminal cut . You used a subliminal cut !
Lt. Columbo: No , quite a few subliminal cuts . From some photos I made . Came in here with Milt last night and we shot some pictures ... It must have been the ones around the lamp ... Those are the ones that did it . Maybe it was that fella .
Dr. Bart Keppel: Let me ... see . May I ?
Lt. Columbo: We had them processed last night , and we cut 'em into your movie this morning .
Dr. Bart Keppel: I know one thing , Lieutenant , you have to admit ... you never would have solved it without using my technique .
Lt. Columbo: That 's right , Doc . If there was a reward , I 'd support your claim to it .
