On a panel marked FLARES, Foyle pressed the DISTRESS button. There was a three-second pause during which he suffered. Then white radiance blinded him as the distress signal went off in three triple bursts, nine prayers for help. Foyle pressed the button twice again, and twice more the flares flashed in space while the radioactives incorporated in their combustion set up a static howl that must register on any waveband of any receiver.
