They called him Bajo el Sol - ‘sundown’ - and his guns had blazed a trail of death across Texas. Now the sundown killer was dead - or was he? Witnesses said yes - but bullet-riddled dead men were mute testimony that Bajo el Sol still lived … and killed.

So Slade had his trickiest assignment of his career as an undercover agent for the Texas Rangers - track down a dead killer … and see that he stayed dead.

Four times Walt Slade had faced Vic Sosna - and four times the elusive killer had escaped the Ranger ace. When Slade’s new assignment took him to Espantosa, he knew it would be tough - but when he found out that once again Vic Sosna was behind the outbreak of lawlessness, he smiled with grim joy.

No mistakes this time, Slade told himself. It’s Sosna or me - and I’m making sure it’s not me! But Slade didn’t know about the ambush Sosna had laid - or the diabolical end the outlaw had planned for him!
