Ellis Vale Cement Co.

In the novel Death in the Clouds, Ellis Vale Cement Co. is the company which James Ryder is the managing director of. Ryder also appears to have a partner, one George Ebermann. In Ryder's pocket there was a letter from Ebermann saying that he hopes Ryder managed to negotiate a loan successfully otherwise they would be "in queer street". This suggests that the company is in some financial difficulty.
