A Mary Rabinowitz Murder Case

Her German shepherd Sabati taking her for a walk, Mary Rabinowitz was tall leggy and blonde the Carole Lombard type. Cast as the black sheep of her Jerusalem family, they had castigated her for not having stubby legs and big boobs. There had been some talk about her mother and a US Navy Officer, but that had died down years ago.
They had named her Mary to spite her. After she learned that Mary was the Mother of God in many circles, the sting went out of it. Sabati had earned his name when his box had arrived on her doorstep during the Sabbath. Twice widowed and still attractive, she needed a big dog around her.
Uncharacteristically, Sabati was growling at the vacated newspaper office to her right. She recognized Nicolai Petrovich as the man hanging from the ceiling. The experience had not improved his looks. Turning his attention to the east wall Sabati issued the low growl usually reserved for an enemy. On the other side of the wall lived the butcher dentist Rothenberg infamous for his hatred of Russians and dogs in no special order. Case solved, she called Sergeant Yosi Peretz.
The only officer on the force not to indulge in extra-judicial murder, he stood out as a black sheep. Her kind of man, she regretted (at times) he was happily married to a beautiful woman. Mary never had a female friend. They were too poor in mathematic logic.
Peretz walked slowly along the perimeter scanning every centimeter floor to ceiling. He muttered. "Who did it, Mary?"
"My guess is Rothenberg."
Yosi laughed. Mary had never guessed at anything in her life. "If we righted the chair used in the hanging, its seat would be at least twenty centimeters under the soles of Nicolai's shoes."
"Sabati was the first to identify the killer."
"Don't worry; I'll credit him in my report."
"One other thing, leave me out of it."
"Yeah, the dentist has eight kids."
