Books like Rhinoceros

I read this in large print but I still struggled to engage in it early in the book but I did finish it .It is the first book by the author I have read but I see there are a number which have adventures with Tweed and his mates so I will be looking out for others before I judge the author too harshly. There were a lot of characters in the book and it took me a while to sort everyone out but the book flowed along and takes the reader to many parts of the world .There are a lot of twists and turns in the book and this kept me guessing to the end , and there were one or two unexpected revelations at the end which made for a good ending
