A calendar usually tells you what is coming. This one looks back. Each month gets a single date, and each date hides a story that history books mostly skip: a novelist who vanished, a woman who nearly killed a dictator, a wrong resistor that kept a heart beating.

She is fifty, Irish, the daughter of Lord Ashbourne, a former Lord Chancellor of Ireland. Mussolini has just addressed an international congress of surgeons. At the moment she fires, he turns his head: the bullet grazes the bridge of his nose. Her second shot fails.

Two years earlier, building an instrument to record heart sounds, Greatbatch had reached for the wrong resistor. Instead of recording, the circuit began to pulse: 1.8 milliseconds on, a second off. Like a heartbeat.
