Alibi

...mighty suspicious they might well have been. However, Marcus had an alibi. He admitted, after being coy about saying anything, that he’d been with a known prostitute. He had paid her handsomely for subsequent corroboration of his story. She stayed around the area for as long as it took for the death to be resolved and then she disappeared somewhere, never to return, but in any event, unlamented.

The police strangely ignored the bruised breasts, bleeding nipples and evidence of bondage wounds. Suspicious, but maybe it was just too difficult to solve and too easy to let the coroner decide.
