A charming, quick-witted woman of a certain age, Dorothy Martin once more finds herself embroiled in a most puzzling crime...and a saga of greed, jealousy and murder.

The victim: a fellow American, her seat companion on a commuter train to London. Dorothy is convinced he was poisoned, yet the authorities' repsonse to her interest is emphatic denial: there was no man, no body, no drime.

Undaunted, Dorothy discovers not only the victim's shocking identity, but a deadly game of corporate rivalry. She takes a job in a London software company, boldly entering the hornet's nest where a cold and calculating killer is waiting.
