Is there any site that I can buy "And Then There Were None" and "Evil Under The Sun"? GOG and Steam don't have them.

fildil, are they listed at Amazon?

No, they don't have any downloadable for the pc.

I've downloaded a lot of games from Amazon, but maybe they don't have any of these. Hopefully someone else will have a better idea!

DreamCatcher was the publisher for these and they failed to pay their developers. These were pulled long ago for legal download.
You need to find someone with a disk that wants to sell.

Thanks, but I really don't want to play from a disk. Maybe I'll try the new Hercule Poirot game.

Yes, they were available from Big Fish as a download years ago and have since been removed there as well.

I do remember that with the first game, And Then There Were None, no CD was required after the game had been installed. Not sure about the other two, but this may have been the case with them as well.

It's been awhile since I have played Evil under the Sun and I do not have access to my game for the time being , still at the cottage and the game is at home but if I remember correctly this game does not require playing with the CD.

Coincidentally, I have just recently installed the DreamCatcher / The Adventure Company 3 CD version of Evil Under The Sun, and it does work without the disk in the drive. There is a patch that I have had for a long time, but I think it is still available on The Patches Scrolls. If not, I could email it to anybody that wants it. It's about 9mb.
