In a time before the science of crime became the solving of it, a detective relied on an open eye, a keen ear and the dogged pursuit of any and every lead. Here in Victorian England, the difference between innocence and guilt can all be weighed upon 'The Suspicions of Mr Whicher'. Charles, the son of Sir Edward Shore (former Home Secretary and man behind Whicher's dismissal from the force) has now come to him with a delicate problem. His son has returned from India with wife and children, only to discover he is being pursued by Lascars (Indian sailors) in search of some kind of retribution. Sir Edward would like this case hushed up and quietly solved; but when murder comes into play, all rules and social etiquettes must be put to aside.
