Type IS is determined at runtime. This is the type of the reference variable that is the object; the actual instance is strongly typed.

EDIT: - , Deserialize, . :
Type tType = Type.GetType(pLoadOut.Type);
MethodInfo method = typeof(ApiSerialiseHelper).GetMethod("Deserialise", new Type[] { typeof(string) });
MethodInfo generic = method.MakeGenericMethod(tType);
Converter<string,ISomething> deser = (Converter<string,ISomething>)Delegate.CreateDelegate(typeof(Converter<string,ISomething>),generic);
ISomething result = deser(pLoadOut.Data);
