Written by a young, pre-Triffids Wyndham under the name John Beynon, this is a less well developed effort that nonetheless shows his talent. The plot is standard, with an attractive female stowaway joining an all-male crew on a race to be the first nation to land on Mars, but it's graced with original details and intelligent epithets such as "Mind is the control of brain by memory," and the fast-paced plot keeps you reading. The most interesting elements are the Martian landscape, the rusty berserk Martian robots, and the sad remains of the Martian people whose cities are like a series of empty rooms. When the story turns into a space romance, you understand why the stowaway had to be female. Wyndham always wrote with a sure hand, and that was no less true of this early effort than of his later, better novels.
