In the Cards by George O. Smith

Unfortunately for Jim Forrest his mansion was not equipped with space radar and so the only indication of the arrival of Jack Turner was given in the control room of Turner's captured ship. Turner landed in Forrest's ship beside his own and viewed the huge mansion wonderingly.

Then, shrugging, Captain Turner checked his blaster, appropriated from Forrest's supply in the pilot room, and stepped to the front door of the mansion.
