Set in the 1970s, and a Russian poet has sought asylum in the U. Days before he qualifies for citizenship, he is kidnapped from Grand Central Station. The opening is extremely descriptive, almost one-step removed from the action, and it takes awhile until you are fully engaged in the two tracks.
Neither one knows the other exists, and the two stories remain fully compartmentalized.
The story diverges on two tracks — a black-bag CIA operative comes in from the cold just enough to maintain full deniability while he looks for the man and an FBI manager keeps poking and prodding trying to find out why.
An individual's skin pigmentation is the result of genetics, being the product of both of the individual's biological parents' genetic makeup.In evolution, skin pigmentation in human beings evolved by a process of natural selection primarily to regulate the amount of ultraviolet radiation penetrating the skin, controlling its biochemical effects.The actual skin color of different humans is affected by many substances, although the single most important substance is the pigment melanin.Melanin is produced within the skin in cells called melanocytes and it is the main determinant of the skin color of darker-skinned humans.The skin color of people with light skin is determined mainly by the bluish-white connective tissue under the dermis and by the hemoglobin circulating in the veins of the dermis.
The red color underlying the skin becomes more visible, especially in the face, when, as consequence of physical exercise or the stimulation of the nervous system (anger, fear), arterioles dilate.There is a direct correlation between the geographic distribution of UV radiation (UVR) and the distribution of indigenous skin pigmentation around the world.Areas that receive higher amounts of UVR, generally located closer to the equator, tend to have darker-skinned populations.Areas that are far from the tropics and closer to the poles have lower intensity of UVR, which is reflected in lighter-skinned populations.Natural skin color can also darken as a result of tanning due to exposure to sunlight.The leading theory is that skin color adapts to intense sunlight irradiation to provide partial protection against the ultraviolet fraction that produces damage and thus mutations in the DNA of the skin cells.
